I did use Lexan brand clear plastic like material. It was Lexan for sure
since I still have a few small pieces with the label on it.
When I said torch, I meant to warm it slightly. I actually used a heat
gun (sort of like a high temp hair dryer) and I held this about 12" away
from the plastic. I did this to ease the "wanna bend back to flat"
tendency of the Lexan after it was installed in the curved window hole.
This was done to make the rubber seal fit a bit better. The apex of the
curves was pushing the gasket out.
Maybe a torch is not a good idea on the Lexan. A common hair dryer may
work best.
Just wanting to clear things up.
