There is a very clear Silicone-like product which I used to install my
windshield. It is packaged in a caulking-gun tube. Someone here must know
it's name. I'll bet it would work well in this application.


Polyurethane caulk, perhaps?

I have never used it in that application, but I know one thing. That stuff
is sticker than cat ****!

It works like caulk, but holds like construction adhesive.

It might be worth an experiment. (on some sample pieces) After all, this
is experimental aviation, right?
