Whats the best way to clean/remove scratches from a plexiglass windshield?The boat cover has worn scratches and rub marks into it?Thanks

I've used Novus plastic polish with success.

There is also a cleaner followed by a polish, (2 step process), from either 3M or Mcguire's. I have used this stuff in the past and have been very happy with the results.

I used to have an acrylic aquarium. This is a great way to remove scratches.

Goes up to 12000 grit!! Very labor intensive though. If you have balls enough you can also flame polish.

Novus... has three levels of abrasive. Works great
