Subject: Stus-List My Experience and Mistakes With Interlux
Brightside/Interlux Prekote
Hey all,
I've got the day off, so I wanted to post my experience as a first-time boat
painter repainting the topsides of my 1976 C 30 with Interlux Brightside and
Interlux Prekote. I made some small, but dumb mistakes during this process.
I'm sure the experts will have a little laugh at my expense, but hopefully this
post will save other first-time painters some grief.
When I bought my boat back in October, I knew I was going to repaint her. The
hull was robin's egg blue... which many people think is a beautiful color, but
I don't. The paint job was sloppy with lots of thick brush marks, and it had
been worn off in a few places from rubbing of her lines and fenders.
This was the state of her hull

I spent my mornings before work this winter rewiring the entire boat - crawling
around in cockpit lockers and getting covered in 40-year-old boat grime. So
when the weather broke and it was finally time to paint, I was excited to work
outside.
I bought 8 cans of Steel Gray Interlux Brightside (A.K.A. Way Too Much... but
more on that later) and 2 cans of Gray Interlux PreKote from defender.com for a
total of $351.90 before shipping.
When the paint arrived, I carefully taped off the toe rail at the top, and the
line where the bottom paint starts with Scotch Blue Painter's tape.
Looking like a CDC agent in my 3m respirator, gloves, and cover-alls, I got to
work sanding. If you read online, you'll quickly learn that sanding is the key
to a nice finish. Thankfully, I took this advice seriously.
I sanded the old paint off using 150 grit pads on my cheap Black and Decker
orbit sander. I sanded until I could just see the old paint disappear, then I
moved on to a new section until I had gone over the whole hull. I then wiped
down the whole hull with a rag soaked in Interlux 333 brushing liquid

I hit those old decals with a blast from my heat gun and they peeled right off.
Now it was time to prime. I was nervous when I opened the first can of
Interlux PreKote because the stuff was completely separated - the solids were
all on the bottom of the can. I thought maybe I had bought bad paint and I was
also concerned that the weather - then hovering around 55-60 degrees was too
cold to apply it. I took my drill with a mixing bit and mixed up the paint as
best I could. This got it to a nice consistency.
Donning zero protective clothing - just an old pair of gym shorts, an old tee
shirt and brand new sandals - I took a foam roller and rolled on one coat of
primer. This primer was very thick and I thought it did a nice job filling
imperfections.
Here's where I made dumb mistake #1: I got covered in paint. I have plenty of
experience with interior house paints, and at the time I thought, "No biggie.
I'll just rise it off with a hose." Hah.
As I wet my hands, the water just beaded up and my hands stuck together. "Oh
yeah. Boat paint."
Not wanting to use nasty paint thinners to remove it from skin, I went home and
used high percentage rubbing alcohol and a towel. With a lot of elbow grease,
this took the paint and a few layers of skin off quite nicely. I then waited a
day for the primer on the boat to dry.
The next morning, I sanded it. Sanding will be a recurring theme in this post.
I used 150 grit discs again and worked to get the surface as smooth as
possible. In tough, uneven places, I sometimes sanded the primer completely
away, trying to get the surface smooth knowing that I was going to apply
another coat.
I then wiped the whole hull with a damp rag to remove the sanding dust and
rolled on another coat of Interlux PreKote - this time with coveralls on.
The next day I sanded again with 220 grit. Got it to a nice, smooth finish,
and wiped the hull down again with a damp rag.
Now before I get into the finish coating, I want to say I have always been
confused by the phrase "roll and tip". This makes it sound way more
complicated than it is. The definition, as far as I know, of the word "tip"
has nothing to do with what you actually do. For the amateurs out there, I
think the process could be more clearly described as "roll and brush".
This is the best YouTube video I've found of how to roll and
tip/brush:https://www.youtube.com/watch?v=k-SGcSlNmoo
The helpful guys at my local West Marine told me to paint a full section of the
boat at one time - IE the
