source for fixed port polycarbonate?

Butyl comes in black as well as gray. Be sure to sand the edges where the seal will be made. I looked at one where the new ports had just fallen off where this was not done, so I have data.

I have the one new 3/8" window from Commercial Plastics in Seattle. About $60 cut out, inside edge radiused and drilled to match the old window. I have been busy sanding and painting a 32' power boat so haven't installed the new window yet. Soon.

Man, here I go again with the facilation. It certainly does seem that the preponderance of opinion is to do it the factory way. BobM's idea of a hybrid, using the butyl tape to seal and position the Lexan, while finishing up with the Dow Corning sealant (I think I have 795) to level off the exterior makes a lot of sense, if the gray tape doesn't show through. I'm not sure you'd get enough grip from the butyl, though, if you have to bend the panel any. My understanding is that the Dow Corning stuff is the same adhesive/sealant that's used to keep glass panels from falling out of skyscrapers, so it's pretty strong stuff, but it's not going to be doing much more than sealing if it's just spread along the outside joint.

And then again, if West Coast Bob's bolted panels lasted ten years in their original iteration, you'd think the newer, more robust version would hang in there quite a while. I do like solutions that I can do without an extra pair of hands and that I can undo fairly easily if I screw up.

don't know about you john but it was very hard to cut out the old panels when i was changing out the plexi panels and that stuff was 31 years old ...so what i am asking you is why would anyone argue with success in regards to this application the Dow 795 is the best choice for this IMHO...yes it is a little difficult to apply but well worth the effort.....
