so after getting lots of advice on these pages from you guys i thought id give some. id been suffering a crappy heavily scratched windshield for quite awhile because someone decided to wash it with a scourer. it had scratches from tit to toe. i looked everywhere on how to fix it and the only info i could find told me to sand it back. thats not something i was willing to try. then i came across something called NOVUS plastic polish, its efin brilliant... i wont go into details on how to use it, you can find that yourself but IT WORKS and works well. within an hour i had all but a couple of deep scratches removed. i got mine from ebay for about $30 and it will last awhile. if you have scratched clear plastic (polycarbonate or whatever) try it , it takes no effort.
