Drag Car windows

I'm looking for some ideas on how to mount lexan windows that can be quickly removed. The side windows will be attached to a fiberglass door. Can lexan be manipulated with heat? Is there a glue that will reliably attach lexan to itself?

The above post is backwards, Lexan is haetable and can be formed in a press brake and cut on a sheare.On the other hand plexi-glass is lower cost but brittle and will chip, crack and is not formable.
I have worked with this stuff for years. For adhearing Lexan I use clear silicone. I have made machine guards and even bullet proof windows with Lexan.For auto windows you can get it with a harder finish outer coating but still requires gentle cleaning.

Might want to try Plexi-glass instead. Lexan is very hard and cracks easy. Plexi-glass is more forgiving and costs a whole lot less than Lexan. :D
My experience is a bit different :) Bending Lexan in a sheetmetal brake is no problem (warm weather, not sure about the dead of winter).
Lexan costs quite a bit more than Plexiglass, at least it does around here.

I've used both lexan (polycarbonate) and Plexi-glass for a variety of projects over the years. I've found polycarbonate to be more resistent to cracking than plexi-glass. In addition, polycarbonate tends to bend rather than shatter into sharp shards like plexi-glass. Yes polycarbonate is more expensive, but well worth it with the safety factor.

I have built aquariums from sheets of lexan using methylene chloride. It is a solvent rather than a glue. It bonds the two pieces together into a single piece, rather than just sticking them together. It takes a little skill to use, but it is the way to go.
Can you advise if methylene chloride would be available locally? Do you need to take any protective measures?
