Here is the tool I use to remone my port lights. Ahter the windows are out, 
you can use it to remove excess sealant.

Hi Gary,

I'm reminded of a quote from John Lennon,

  “Everything will be okay in the end. If 
it's not okay, it's not the end.”


Good luck with the window project. It's a 
seasonal thread here, kinda like Christmas but without the merry.

Hi Pete,
 I spent about an hour yesterday with the

Plexus.  That leaves me about 16 hours of 
grinding to go.  I'm not afraid of work, but 
the damage done was extensive.  And as I get 
more tired (remember the 16 hours), then I 
will get more careless and do more damage.  I 
tried making a fixture for my router to remove 
a window with the adhesive, and it would 
probably work, but one slip of the fixture and 
I would have a hole through the coach 
roof.  The finish was nice, but in the end, I 
though it too risky.  Also, the fixture would 
only work with an intact window and would not 
clean up the damage from the window I've 
already removed.  At this point I am really discouraged.

Dave,

I took a look at your new blog post detailing the tools you have used on the 
window frame clean up.  Nice write up, thanks.

I am jealous about your having access to compressed air and working where you 
can use it.  Where Calypso is moored there are restrictions on what work can be 
done in a slip.  I am already dancing down the line with electric 
sanding/grinding equipment and I am sure running a compressor and air tools 
would get me kicked out.

I believe many of the cnc-listers that are facing a DIY window or other deck 
repair/replacement project need to limit the mess, repainting, or do not have 
the experience and confidence to perform “body and fender” type work on the 
shiny parts of a boat.  I recall the day when Calypso’s co-owner and I finally 
faced up to the amount of repair Calypso’s deck needed and accepted a full 
repaint would be needed.  Once freed from the need to limit shiny paint damage 
we got out the big boy grinding and sanding equipment which greatly sped up the 
early phases of the repairs.

This month marked to point where way more hand sanding is needed with the 
resulting wear and tear on the arms and wrists (as you mention in your blog 
post).  I have been using hand sanding blocks and foam shapes (purchased from 
auto body repair equip sources) to improve the hand sanding ergonomics 
especially around the many corners and rounded shapes of a C  The sticky 
back sand paper option increased efficiency over the old school paper clamps.  
I have had good luck sourcing abrasives through several web sites including 
Industrial Abrasives.

Re: Stus-List Fwd: Replacing Windows

[Russ & Melody via CnC-List]

Hi Martin& Dave,

I've been involved with 4 in-the-water boat deck 
restorations here in an area just north of the 
PNW, (around Lat 49' 10 - 30" N.)


Since winter is a good time for in-the-water boat 
work in our area, all were covered with a 2x4 & 
1x4 framework peaked over the boom and covered in 
plastic (poly or trap) down to the 
toe-rail.   All marinas have a "no sanding" 
policy but not one of us suffered a complaint, 
maybe due to the containment, lack of traffic at 
this time of year and good vacuum practices.  Or 
perhaps because we are all, just good fellows. I like to believe the latter. :)


As you might imagine, these enclosures are very 
pleasant to work in during our typical winter.

Re: Stus-List Fwd: Replacing Windows, Multi-Tool

[Gary Russell via CnC-List]

Hi Alan,
 I am having trouble understanding your description.  I assume the
first step with the pattern bit is to cut out the new window and the second
step is to remove the old window.  If this is true, then I am concerned
about controlling the router in the second step so as not to damage the
area around the old window.  Is your old window recessed as mine is?

Re: Stus-List Fwd: Replacing Windows, Multi-Tool

Hi Gary, 
When I do my windows, I plan to try that tool with a blade like this: 

http://multitoolblade.com/bosch-multi-x-oscillating-multi-tool-blades/1-1-4-flush-cut-diamond-blade.html
 

It might help to heat the window edge first with a heat gun? Or heat the window 
acrylic on a cold day, to help break the glue bond.

Hi Martin and Josh,
 That is exactly what I tried yesterday.  I used a Multi-Tool with a
triangular carbide rasp.  I found it so hard to control in such a confined
area that it did more damage than good.  In particular, the gel coat is so
much softer than the Plexus that it gouged the gel coat as it broke through
the Plexus.  Because the rasp is perfectly flat it is difficult to keep the
corners from digging in if the rasp isn't perfectly flat.

Re: Stus-List Fwd: Replacing Windows

Gary – 

I took out one of my Plexus installed windows a couple weeks ago using a dremel 
oscillating tool (analogous to Fein multi tool).  One has to be careful, but it 
worked surprisingly well.  It’s plexus, so there will be repair work needed to 
the gelcoat.  I’m fortunately done will all that work and will install a new 
lens in a couple weeks if the weather holds.  

 

Holler if you have questions.

Re: Stus-List Fwd: Replacing Windows

[Gary Russell via CnC-List]

Hi Pete,
 I spent about an hour yesterday with the Multi-Tool and the carbide
triangular rasp, and I managed to grind away about 3 feet of Plexus.  That
leaves me about 16 hours of grinding to go.  I'm not afraid of work, but
the damage done was extensive.  And as I get more tired (remember the 16
hours), then I will get more careless and do more damage.  I tried making a
fixture for my router to remove a window with the adhesive, and it would
probably work, but one slip of the fixture and I would have a hole through
the coach roof.  The finish was nice, but in the end, I though it too
risky.  Also, the fixture would only work with an intact window and would
not clean up the damage from the window I've already removed.  At this
point I am really discouraged.

Hi Doug,     While I am quite confident your tool will work well with sealants, 
I don't see how it will work with Plexus which is harder than the acrylic it

Re: Stus-List Fwd: Replacing Windows, Multi-Tool

[Chuck S via CnC-List]

Hi Gary, 

Multi-Tool: 
The putty knife shaped blades have teeth. There are different blades for wood, 
steel, and even masonry. There are round blades too, and even diamond coated 
blades. These tools are really nice to use and can fit into places nothing else 
will.

Re: Stus-List Fwd: Replacing Windows, Multi-Tool

[Alan Bergen via CnC-List]

When I removed my windows, I used a router. Use the new window and double sided 
tape to hold the new window in place. Then use the router with a pattern bit to 
go all around the window. Remove the new window, and use the router with a 
straight bit to remove the rest of the window where it's held by the plexus.

Gary,

Don’t get discouraged. It will work out.

That’s what I sleep telling myself every day...

Since most of the other posters have offered really good suggestions I decided

Hope it helps.

Re: Stus-List Fwd: Replacing Windows

[Robert Boyer via CnC-List]

While this may not apply to windows, I used VHB tape to bond my one solar panel 
to a corrugated plastic sheet used to keep the solar panel cool on my hard 
dodger.  After a year and a half I had to replace the VHB tape because it got 
gummy from the heat and allowed the solar panel to slide aft by about an inch.  
I changed the design since so I didn't have to rely on the VHB tape.  The funny 
part is that the VHB tape was not under any significant load.  I would really 
have my doubts about the longevity of VHB tape on windows without some other 
sealant or adhesive.

Re: Stus-List Fwd: Replacing Windows - welcome

[JP Mail via CnC-List]

Me too. She's an '84 35mk3. Though not perfect, appears to be very well cared 
for and well outfitted. Has new port lights, recent rod rigging, fuel tank and 
rebuild of 3gm. Interesting thing about window refit is a ss frame around them. 
Haven't seen that in my research before. Things I need peace of mind with is 
hull integrity and hull/deck joint. There is also a bead of silicone along toe 
rail. This raises an eyebrow.  I know a 30 year old boat will have issues but 
there are issues I can deal with and others I don't have the time or energy to 
deal with.  I've done the soda blast and hull surface restore before and can do 
it again, but I don't want to face recoring. After a year search I'm settled on 
a C though. Hence joining the list.  I think the 35 mk 3 hits all the buttons 
for me. 
Jon.

Re: Stus-List Fwd: Replacing Windows

[Marek Dziedzic via CnC-List]

One thing I noticed in these specs is that the VHB tapes have generally better 
strength of bond when a dynamic load is applied and “will tend to show creep 
behaviour with stress load acting over a long period of time (static pressure). 
As a general rule, for static loads, approximately four square inches of tape 
should be used for each pound of weight to be supported in order to prevent 
excessive creep.”

I am not sure, but it seems to me that for bonding windows to the cabin top, 
this might be an issue if the windows are curved. Curved windows would try to 
detach themselves from the fibreglass to which they are attached. So unless you 
have some other way of keeping them curved, the tape might not be the best 
option.

just a thought.

The attached PDF had pretty good guidance.  I would choose the thickest tape 
which can still fit under the windows.  Maybe even double layers.  I have a 
friend who used the 4941 series.  After looking at the PDF it looks like the 
5952 series has better adhesive qualities and possibly higher adhesion for the 
fiberglass and polycarbonate that we're using.  The 5958FR has the highest PSI 
to thickness ratio.  I suggest thicker to allow the tape to press into any 
irregularities.  Thicker also allows for more differential expansion of the 
glass and frame.

As much as I like the VHB tape I still can't help but think to the auto 
industry.  They use a urethane made by Sika for windshields.  It has to be 
primed and heated.  It cures in about an hour.  I wonder if a combination of 
VHB tape and sika-flex might be smart.  VHB to get a nice interior finish and 
sika for a permanent weatherproof bond and glazing.

Sikaflex 295 UV is rated at 160 psi.  60% stronger than the highest rated

Re: Stus-List Fwd: Replacing Windows

[Dreuge via CnC-List]

Besides being bulletproof,  a good reason for using polycarbonate is that it is 
much more flexible than acrylic.  You do not have to force it, it will almost 
noodle its way to fit on the curved surface.   The drawback of using 
polycarbonate: cost, UV degradation, and surface scratching, are less of an 
issue these days.  Bayer makes an extended abrasion and UV resistance 
polycarbonate called  Makrolon 15.  A piece of 1/4" x 10" x 43" transparent 
grey goes for $35 at EStreetPlastics.com .

Re: Stus-List Fwd: Replacing Windows

[Dreuge via CnC-List]

Maybe you did not have a clean surface for the VHB tape to properly bond.   

I broke off the passenger rearview mirror from my car when my spinnaker pole 
rolled off of the car roof(it was one of those moments).  The mirror was only 
hanging by the adjustment cable.  At first, like anyone, I used some duct tape 
to hold it back on, but after that failed I used some left over VHB tape.  I 
cleaned the surfaces with MEK, and stuck the mirror back on with VHB tape.  I 
have almost forgotten that it is broken.   That was last spring, and so far the 
VHB tape has survived the FL summer heat without any issues.

Re: Stus-List Fwd: Replacing Windows

[Dreuge via CnC-List]

Bruno,

I solved this problem by aligning the windows before removing the protecting 
film from the VHB tape and hanging the windows in place with two strips of wide 
masking tape from the top side(like two big hinges). You can take the time to 
align the space just as you want(i.e. readjust the masking tape), then lift the 
window up from the bottom while it is still hanging from the masking tape, 
remove the VHB film, and gently swing the window into place.   This is how did 
it with ports up to 50” long on the LF38.

Removing old windows. 
Someone earlier suggested using a MultiTool with the "putty knife" like blade. 
Fein made it first and there are many copies. Harbor Freight has it on sale. 
That's what I'll use.

For those that have done the job, how did you manage the removal of the old 
windows? I imagine I'de destroy any gelcoat down there if I gave this a try.

Hi Chuck,
 Let me assure you that Plexus MA-320 is as hard as a rock.  A putty
knife blade will not touch it.  I spent a good part of today trying to
grind it away with little progress.

Re: Stus-List Fwd: Replacing Windows

[Jake Brodersen via CnC-List]

Dave,

 

I think I’ve finally been converted over to VHB tape.  After seeing the video 
and seeing the comments on here, that is what I will probably use the next time 
I do windows.

The process seems very straight forward and only requires one person, who is 
not in a rush to get done before the adhesive kicks off.  

 

I’ve done my windows twice with Plexus.  Yes, it works, but I certainly would 
like to see the installation last longer.  I think the VHB tape would outlast 
Plexus.

More response to this thread; I’ve been working on the fixed ports on my boat 
over the last few days and and paying close attention. After absorbing a good 
bit of the info in the thread and the links provided, I’m planning on moving 
away from using Plexus ("if it was good enough for my grandfather it’s good 
enough for me!”) and using the 3M tape. Seems the more modern ticket to me.

 

I’m anticipating the operation to be a good bit easy than using Plexus, 
certainly if it is just one person doing the job.

"I’ve done my windows twice with Plexus.”

I know. I still have some Plexus remnants of your last project in my 
refrigerator. ;-)

At the rate that I am moving on this project I would have overrun the shelf 
life anyway so another reason to use the 3M VHB tape. I replaced the ports 16 
years ago shortly after we purchased “Ronin” and used, at the recommendation of 
the portlight fabricator, silicone sealant. Although it did hold the ports in 
and kept things dry, they were never terribly stressed. Based on what I know 
understand I would not recommend that method.

Re: Stus-List Fwd: Replacing Windows

[Dave Godwin via CnC-List]

Rob,

Agreed. When thinking about the tape I did a quick Internet search and came up 
with many versions of the VHB tape. 

I use a software package (OmniFocus) for project planning and under the “Fixed 
Ports Repair” list of actions is a new one to investigate the types of adhesive 
in more detail. With a completion date a good ways in the future I’m afraid...

Gelcoat is just pigmented polyester AFAIK, so I would go with polyester if it 
isn't going to show anyway. (note, some gelcoats may be based on epoxy) Styrene 
applied before the polyester may help to make a better bond.___

Re: Stus-List Fwd: Replacing Windows

[Josh Muckley via CnC-List]

I like the VHB tape method but wasn't there some discussion in previous
posts about the structural properties of the various sealants?

Is this or should this be a concern?

VHB is a product line with various thicknesses and bond strengths so it is
important to make sure you know what you're getting.  3M makes industrial
products in the VHB line so it might be worth adding individual to the
search.

Stevan, mine just popped out with a firm rap from my hand. Had to fix up a few 
small patches of gelcoat but nothing major.

Re: Stus-List Fwd: Replacing Windows

[Dreuge via CnC-List]

I used epoxy filled 50-50 with colloidal silica & 3M glass bubbles. Without 
the 3M bubbles, sanding the thickened silica epoxy mix is like sanding a rock.

Re: Stus-List Fwd: Replacing Windows

[bobmor99 . via CnC-List]

A very important distinction (made before by others) when talking about
rebedding windows/ports/port lights is whether the window is the old style,
i.e. aluminium frame attached to the cabintop and a lens attached to the
frame or, the newer style which is a lens glued directly to the the outside
of the cabintop,

This distinction eluded me for quite awhile when reading threads about
rebedding windows/ports/port lights.

I have the old style windows and am very happy using butyl to seal the
frames to the outside of the cabintop (along with the screws that attach
the frame to the cabintop). (Here, there's a difference between attaching
and sealing.)

The newer windows/ports/port lights rely on a very strong adhesive to both
attach and seal the lens to the outside of the cabintop.

Hope this helps,

Dave, I checked your blog and that's an impressive effort there on the
refit. I hope the VHB works out for you.

Ahmet, I hear butyl is good for the aluminum frame portlights on the 70s
C The fixed port lights on the 80s boats are supposed to be structural
so they have to be bonded to the cabin top.

Not quite the same thing but lately I've been removing ports that were held
in with sealant by using a vibrating saw with a caulk cutting blade.  Like
these:

http://www.amazon.com/Bosch-OSC214C-4-Inch-Caulk-Knife/dp/B004UBF43S

Not sure how they would work on Plexus or Sika adhesives.

Hi Dennis,
 I'm quite sure those blades would work well for soft calk like
silicones or urethanes, but Plexus is hard as a rock and I don't think they
would work.  In addition, the big problem is getting at the bottom window
joint that is very close to the turn on the deck.

Butyl tape is a terrific sealant.  I use it all the time.  It is not an
adhesive, however, and should not be used to bond windows to fiberglass.

Re: Stus-List Fwd: Replacing Windows

[Gary Russell via CnC-List]

Hi Bruce,
 Welcome to the C forum.  Some members get a little cranky, but most
are wonderful folks that just want to help.

 First a few basics.  Plexiglas is a trade name for acrylic and Lexan
is the trade name for poly carbonate.  Poly carbonate is known for being
bullet proof, but easy to scratch.  Acrylics are more scratch resistant,
but not as tough.  If you are in trouble with the mob, then by all means
use poly carbonate otherwise acrylic is probably a better choice.  I don't
know how to tell the difference between the two.once installed.

 Don't quote me on this, but I think VHB (Very High Bond) can be
separated with a razor blade driven between the surfaces.  After that
delicate scraping is probably involved.  Anything is better than Plexus.
It is almost impossible to remove.  You can grind it out, but if it is in a
recess, then you have to worry about damaging the surrounding area.

Best of luck,
Gary

Re: Stus-List Fwd: Replacing Windows

[Dave Godwin via CnC-List]

More response to this thread; I’ve been working on the fixed ports on my boat 
over the last few days and and paying close attention. After absorbing a good 
bit of the info in the thread and the links provided, I’m planning on moving 
away from using Plexus ("if it was good enough for my grandfather it’s good 
enough for me!”) and using the 3M tape. Seems the more modern ticket to me.

I’m anticipating the operation to be a good bit easy than using Plexus, 
certainly if it is just one person doing the job.

Cheers,

Hi Josh,
 I have been thinking the same thing.  So far (only removed one window)
the damage has been contained under the glazing.

Re: Stus-List Fwd: Replacing Windows

[Josh Muckley via CnC-List]

I'm not convinced that repairing the gel-coat is critical unless the damage
extends beyond that which is hidden by the window and glazing.  I'd just
use silica filled epoxy.  Scrub it well to remove the amine blush and then
maybe give it a little tooth by sanding it dull.  The typical 80 grit might
be a little much but just remove the shine.

Yup, you will!  The question is, what is the best way to repair the
gelcoat.  I have glass mat showing in places.  Do I apply epoxy or
polyester resin to the glass mat before filling in the damaged area?  What
do I fill it with?  Should I use MarineTex or silica filled resin?  help!!!

  It amazes me that people with no marine design experience would change the

 The problem with Lexan (which is a polycarbonate) is that it is
 less scratch resistant than Plexiglas (acrylic).  You are probably trading
 one problem for another.

  As for Plexus vs Silka 295, I am really torn.  The write-up in the
 Photo Album suggest that Plexus will be flexible enough if (big if) the
 bond thickness is large enough.  To that end he added glass beads to the
 adhesive to make sure the bond thickness didn't get thinner than 0.030".

  Thoughts, anyone?

 Please note that the 3M VHB tape is available in black, eliminating (I
think) the need for Fusion Black paint.

 The problem with Lexan (which is a polycarbonate) is that it is

  As for Plexus vs Silka 295, I am really torn.  The write-up in the

 I sent you the process I used 'off list'.

 The 2 forward windows on my boat are also curved.not exactly sure
 how much but it is noticeable.you can get a better idea when you take
 the old windows out and lay them on a flat surface.   I used Sika 295 UV
 with the Sika primer and I also wondered if this adhesive would hold the
 curved window(s) in place.  It's been 6 seasons and no problems.

 Before installing the new windows, I wondered how I was going to 'brace
 them' while the Sika cured.  I explained all of that in my 'off list' email
 to you.  Any further questions, don't hesitate to ask.

 Fred,
  The VHB tape with DOW Corning 795 Silicone Sealant is starting to
 look like and attractive method.  I am replacing the windows over the
 winter, also.  We should keep in touch.  Do I assume you would use the gray
 VHB tape with the gray silicone sealant?  I am wondering if the VHB tape
 will be a problem with peel.  My cabin sides are curved, so the windows
 will have to be bent slightly to conform to the side of the cabin.  I
 wonder if that will be a problem with the 3/8" thick acrylic trying to
  return to a flat shape?
