Can someone please advise on how to and what product is best?

the 3M head light restore kit. but I couldn't get the headlights back to 100%

Thanks...do I need to take the lights out?

Not necessarily, just tape around them really well.

I'd suggest posting some pics of your current headlight and what you'd like to do. You may be able to just get by with some rubbing compound or polish, or wet sand and save a few bucks if you have stuff already, depends on the current condition.

I got to stop being lazy and use some M105 on my headlights :O, these threads keep reminding me lol.

Thats what I ended up doing did a real nice job. I used my new Porter Cable 7424 XP (From Detailed Image of course) a yellow cutting pad and some Menzerna PO106FA. Looks great and what was somewhat grainy surface is now smooth as glass.

yeah I just did this for my dad for ***** and giggles.... his car broke down on the highway this weekend coming up to visit me so I replaced the water pump this week, got that done so I have some time until he comes up here in a few days to pick it up.



The light was really yellow in the first pic but doesnt show very well.... still has come yellowing, but I am guessing that is deep in the lens since it is a '95 p/u truck.

Process was 600-1000-2000-yellow/SIP (PC) - white/Opt I (PC) - sealant by hand

took about 1/2 hour I guess.... And I am a complete noob, headlights are great to practice on, no clear or base coats to worry about going though.....

I am thinking the OP's process should be quicker since you prolly wont need to go as aggressive with a newer car, but depends on condition.

get meguiars plast X and get some of that rough green sponge from the dollar store that they sell to remove grime from dishes, comes out like new

3m Rubbing Compound works good for me... no taping around anything

3m rubbing compound works fine.

Make sure you apply a polish/sealant over the lights when you get them cleaned or they will start to discolor quickly.

Windex and paper towels...

LOL, I was just thinking today how much the yellowness of my headlights bothered me (just got my G earlier this year) and so just this afternoon I took care of it. If I had a power buffer I could have done a *spectacular* job but I don't, and ended up doing it by hand.

Anyways, I simply wet-sanded the headlights with 1500 grit sandpaper until I was satisfied, rinsed the headlights and dried them. Then I used an applicator pad to rub in Meguiar's PlastX until I had an even film throughout. I wiped away the residue with a microfiber towel, and lastly used Meguiar's Polish on the finish. I'm rather happy about the results myself...I forgot to take a before pic, but we all know what yellow haze looks like. Here's the result:

toothpaste works perfect! old school cheap and simple
