there is a....last ditch trick.
I learned this in autobody class years ago, and still dont believe it when I see it done.
They had the plexiglass dash panel off an old car, needed to be cleaned. It was heavily hazed/with swirl cracks,yellowing...sucker was 30 years old.
The Rep from DuPont Paints came by, and showed us the deal. He used Meiguires wax with a buffer..a FOAM buffer. You CANT burn paint or plastics with foam...its too hollow, it wont hold heat. Heat is bad...thats what burns paintjobs when buffing.
He applied the wax to the plastic...10 minutes later..it looked new..BETTER than new.
Pratice found that toothpaste works just as well, as long as you follow it with a finish swirl remover-then finish wax. It WILL work on plastic windows IF you have something behind it to apply the pressure....Ive seen old jeep plastic windows that were white come back to absofrickinlutey clear as glass....it takes time, but its cheaper than new....we like cheaper.
and if your really good....it can be used to make old windshields good again...no wiper marks.....
