there some light swirl marks on my fastback tail lights, what should i use to buff those out? I want it to look like glass. I want to make them smooth, then mask off the clear part of the lens, and use some niteshade spray to darken up the black parts, like GoKart did .

Try using mothers plastic polish it worked great on mine

Ill give a try thanks. Does it leave any residue or anything? Will i have problems applying that tint spray after? Would it be a good idea to clearcoat over the spray?

I have used Meguires plastic polish with great results.

3M also makes a plastic cleaner/polish option, but I've only found it online (it works well too).

If the marks won't come out with just polish try using wet 2000 sand paper and then polish. I used this on hazy motorcycle instrument lenses and they turned out beautiful. The first time you use sand paper after polish the paper will gum up quickly. Use lots of water to keep the paper clean.

toothpaste, for small scratches.
