I wish I had known about VHB tape a few years back when I replaced the
windows....it sure would have made the job a lot easier than the Sika
295 UV .....if I ever have to do the job again, which I hope will never
happen, I will use this tape method.
Thanks Gary for pointing this out and the video.

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?

Gary — I’m going to be replacing the fixed windows on my LF38
over the winter. I’ve done the Plexus thing twice now
(previous boat); this time, I’m going to try the VHB tape
with Dow 795 approach, like Paul did on Johanna Rose:

I’ll be using 3/8” bronze acrylic with a chamfer to the
outside edge.

Hi Paul,
I agree that 1/4" is too thin. The other 37+ at my club
has 5/16" It amazes me that people with no marine design
experience would change the design. I plan to go with 3/8"
acrylic. But then again...
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?
