not sure on Lexan...we mostly were using plexi to make refugiums for salt water aquariums. No one liked the cut edge look. It's called flame polishing.
Wow my ears must have been burning. I was just about to post my findings.
Lexan did not work well. (for me anyways) I think it reacts to heat much differently than plexi glass. I tried it on some scrap pieces of Lexan I had . I cut and sanded them to as fine as I could but it melted very quickly, unevenly and milky.
I also checked the OEM windshield and it looks as if the finish is a very fine diamond finish. My home made lowers are pretty close to the windshield finish so I will leave them alone.
Thanks for your post.
P.S Varsol/Paint thinner works great on Lexan for removing the paper backing etc. I am not sure about Plexi glass. I ruined my first attempt at lowers by trying to remove the backing glue from Lexan with an alcohol based agent that I read about on another unreliable forum ....
