Hi Everyone, I have some plexiglass/acrylic/lexan questions, 1. I tried to tint the piece with the DIY stuff from the local autoparts store. Messed up, ripped it off and re-applied with new tinting film. There are bubbles and crap under the film, evidently left over adhesive from the previous attempt.
What can I use to clean this off? There was another post on plexiglass which mentioned alcohol, etc. Will acetone or lacquer thinner cloud it up? I really don't want to buy another piece of plastic.
2. Can light scratches be sanded then polished out? I have the gear for color sanding and polishing/buffing for automotive clearcoats. Will this work on plexiglass too?
3. Anyone know of a protective yet clear film for protecting the plexiglass from scratches, fading, etc? Clear spray paint sold at autoparts stores? Automotive clearcoat?
PS. I've seen a lot of cutting tips on this site, here's mine. I use a thin cutting wheel for metal, like the kind you put on those handheld 4" grinders. It works wonders, as with any project, you'd want to leave a little margin before going all the way in. I did a lexan rear window for my car - put the grinder in a vise on the floor, and dragged the plastic over the grinding wheel, following a line I drew on the plastic. Just make sure you're not getting the wheel too deep into the plastic or it will catch and possibly snap the plastic.

acetone might be a little too harsh. try it on a spot that wont be visible or some scrap. if not you might try a chemical called Naptha. its like alchohol but weaker. its used to clean very high temp glass. like the bulbs in search lights.
as for cleaning it. wet sanding with high grit paper should take off any nasty shmeg. then to clean make it crystal clear polishing compound will work. its like a past with a very fine grit to is. simailer to car wax in application.
