most headlights will clear up with 1500, then 3000, then a polish via rotary. The thing is you have to seal them up, or re-clear them so the yellowing/oxidizing will not take effect so fast!

 

Nice work

 

If you get the Meguiars on your headlights when the fogging is in the early stages, you will be able to avoid the yellowing/hazing that becomes a job to remove.

 

I just bought and used the 3M Headlight Restoration kit on my headlights which were literally eaten up and cracked from a chemical. This made my headlights look brand freaken new I am VERY impressed. Only thing that sucks is that I can see fine scratches all over the light snd wet sanding and compound wont take it out.

 

I just bought and used the kit. It is on sale at Napa for $16.98 with a mail in rebate for another $3.00.
My lights look much better but still a light haze. I have used 2 kits and still have fine scratches. I assume I need to do more 3000 sanding and polishing.
Any particular brand/type of clear coat recommended for a top coat when I get the headlights the way I want them?

 

I've been using toothpaste for >20 years on plastic headlights and then finishing the process with Collinate #845. Toothpaste has a polishing compound, which is just as effectove than the more expensive products being sold for this.

Just take about 1/2 teaspoon and hand or towel rub it on the headlight for about 2-3 minutes. Use a slight amount pressure (5-8lbs), rinse and repeat the process 2-3 times, then completely rinse the headlight and dry it. Once dry, apply 3-5 coats of a good wax or sealant that is long lasting (Collinate, Black Magic, NuFinish-- you're looking for durability and not depth). Apply a coat, buff out and wait a few minutes, reapply and buff, wait again, then apply and buff. This should last 4-6 months, even in the winter snow with salt on the roads.

It takes less than 20 minutes total and costs about 25 cents.

 

That's what my bodyshop man said, no need to clear coat, just give it a good hard wax.

 

Yea man I wouldn't mind trading my 04 headlights for the paintwork on the new projectors and grill. Just lemme know what deal you are thinkin

 

Great results!

When I need a deep headlight cleaning, I wetsand (1000 -> 1500 -> 2000 -> 2500) then follow up with Plastx. Comes out like new!

 

+1 yep, it was the best part of my clear bra investment, the material on the head lights is a little thicker than what is installed on your paint, but after 6+ years, my head lights still look brand new!
