Gary: I see. Thank you. This is why black sealant makes sense (as opposed to one that is close in color to the gel coat).
Josh: Will do.

Finger trowel and remove as much excess product as possible. Make it look real clean and then immediately pull the mask at an acute angle.

But you need to use your finger to "trowel" the sealant behind the Plexiglas. That is what is special about the Dow Corning 795 is it has a longer "working time". The Plexiglas probably won't be as tight fitting because of the 0.090" thickness of the VHB tape. That 0.090" gap is what you will be filling. Good luck, Gary ~~~~~~~_/)~~~~~~ On Wed, Dec 13, 2017 at 10:40 PM, Matthew L. Wolford via CnC-List <[email protected]> wrote: Thanks, Gary. So in your view the sealant needs to not only fill the seam between the edge of the plexi and the boat, but also work behind the plexi a bit. Is the pressure of a caulking gun sufficient to get this done? On my boat, the plexi is tightly fitted into the cavity. Perhaps I should leave a little more room with the replacement plexi?

You need to leave room for the Dow Corning 795 black silicone sealant. To me, 1/4" for the sealant seems about right. That leaves room for about 1/2" of VHB tape.

Wolford via CnC-List <[email protected]> wrote: Listers: I know this topic has been covered ad nauseum, but I have two questions about window replacement: 1) It appears that most of you who have done the VHB tape method like 3M 4941 instead of 5952. However, when I contacted 3M and explained what I was using it for, 5952 was recommended. Any thoughts or comments on this? 2) It appears fairly well settled that 1/2" width is preferred (maybe due to Don Casey), yet some of you have mentioned coloring the area behind the window that is not taped to improve the appearance. The window "cavity" (for lack of a better term) for my windows sit is 3/4" all the way around (except for possibly the rounded corners). Why shouldn't I just use 3/4" wide tape? Have at it, and thanks. _______________________________________________ Thanks everyone for supporting this list with your contributions. Each and every one is greatly appreciated.
