How you install Lexan (polycarbonate) doors vs. plexiglass (acrylic) bubble doors are two totally different animals. The Lexan will tolerate most anything without cracking- rivets, screws, tighter torques, bending, etc., but is softer and more easily scratched and fuel stained. The plexiglass bubble doors , and windshield, are where all the extreme care must be taken, but you get a harder, more durable, clearer, and stain resistant result.
