watched a chemical guys video on youtube where he took the foggyness of a bmw headlight out. the thing looked better than brand new.

he first used 2500 grit wet sanding paper then 3500 grit wet sanding paper then used v34, v36, and v38 buffing compound which claim to remove scratches from 1500-3000 grit paper and polish. this problem is there 30 dollars a bottle and then you got to buy 3 buffing pads.

so if i used 2500 and 3500 grit sand paper on my headlights what are my options for compounds out there to finish it off and also a uv protector to make it last thats not going to cost me over 100 bucks.

 

Take a look at the 3m headlight restore kit. It runs ~$25 a kit.

I've used it many times and highly reccomend it.

 

I second that. Very good kit, it comes with everything you need as long as you have a drill. It takes a little time, but the difference coming out of the headlights is literally night and day lol. I used it on my cousin's accord, and those lights look like they are brand new.

 

Ive done like 60+ sets of headlights and here is my method

1. blue tape around headlights

2. 600 grit

3. 800 grit

4. 1000 grit

5 1500 or 2000 grit

keep wet at all times

and lastly a rubbing compound like meguiars 105 or rough

finish with a cleaner wax or sealer

 

Toothpaste!

 

toothpaste actually does work due to the abrasives

i usually just use some high cut compound followed by some polish, unless wet sanding is needed.

 

If you can see yellowing / clear coat peeling then go ahead and wet sand.

 

I third that! It's a solid kit for the $12 (on sale) I paid to do my set of headlights!
