yeah, what he said, just work your way up to 1000 and you will be fine.

 

And mistake 320 for 1000? Damn, 1000 feels like a low quality piece of paper lol.

 

ya ur good, just sand it with a 600's grit, then an 800's grit, then a 1000 grit. i dont know the exact numbers, just reference. you basicly just wanna get all the scratches out by working it up, then use a polishing compound on it.

 

^+1 to what he said about sand paper. I just used the rubbing compound they had at the shop here it comes in a blank gallon jug so im not sure what brand it is, i used the polish from walmart ;-) but the rubbing compound really did all the work. also I used a really nice buffer not one of the little hand ones.

 

Here's an alternative to those expensive headlight restorer kits. Brasso.

I first learned of using Brasso to polish plastic from my optician, back in the 60's when I wore hard contact lenses. Whenever I visited him, he'd take them to the back and in a few minutes they'd come back crystal clear and much more comfortable. I asked him what magic potion he used and he confessed it was plain old Brasso!

I actually bought a headlight restorer kit recently. After doing one headlamp, I remembered Brasso and tried it on the other side. The results were as good if not better than the kit. The kit is better, though, if you have some scratches to fix first. Of course a correct regimen of sandpaper would also work.
