[hdavis]

Has anyone had any luck polishing Plexiglass?

My '67 has Lexan quarter windows and rear window. I use Meguiars Mirror Glaze #17 Plastic Cleaner followed by their Mirror Glaze #10 Clear Plastic Polisher. Works very well.

It is like polishing anything else your progress from coarse to very fine which for optical sufaces is like 12,000 grit sandpaper then to polish.

Thanks Guys, I was about to pony up $225 for a new one, so it's worth trying everything else first.

OK...now you're in my territory. I'm the guy who listened to Mr. Robinson in The Graduate. I am in the plastic sheet business. The best product I've experienced is Novus. They make a #1 for cleaning and shining, #2 for fine scratches and #3 for heavier scratches. If these three don't work then your scratches, scrapes or whatever are too far gone. These products also work very well on those clear flexible vinyl cabriolet rear windows. Google Novus to find a store near you that stocks this brand. MHO.

Any ideas for polishing small scratches and abrasions out of glass? I'm working on a new 911 project that has some scratches and abrasions on the rear window. It would be nice not to have to replace the rear window. Thx.

Thanks Leon, will give Novus a try, especially interested in the flexible vinyl cabriolet application.

When you polish individual scratches, always go "with the grain" ....not against it. i can't tell you how many hardtops i have polished the rear windows on!

I'll second the use of Novus. I've used it on Lexan/Plexiglas/Perspex in a variety of applications (automotive, aircraft, boats, household and even children's toys) with great success.

As pu911rsr wrote, proceed from coarse to fine, starting with #3 and finishing with #1.
