So i bumped into an old friend at autozone over the weekend while i was shopping for a headlight restoration kit for my 350z.

He recommended NOT to use any products found there cause they were all abrasive types and would eventually make my lenses worse. The worse ones where the 3M sanding pad kits.

He later then recommended this liquid from ebay and sent me the link below.
He used it on his Inifiniti and took care of his plastic headlamp covers.

Any thoughts? (please dont start judging because its from fleabay )

 

Why don't you buy it and try it? Then let us know the results.............

 

Tell me about the 3m kits. I ****ed up my headlight

 

If you read some of the feedback left on his feedback page, it doesn't seem to work very good.

 

I simply use my medium polish with an orange pad, followed by a finishing polish with a white pad, then I use my sealant at every detail and my lenses look brand new with no issues. No extra expenses above your normal detailing supplies.

 

i ordered one, on its way, costs $8 shipped and going to try in my daily driver car and see the results from that.

 

I use Meguiar's PlastX with very good results. It is a chemical cleaning agent. Have you looked into this product?

 

Keep us updated.

 

I agree that if you just use one aggressive polish and don't follow up with the proper steps you won't do yourself much good. If you want to truly restore your headlights I have not used one non-abrasive formula that does a great job though. The non-abrasive formulas have helped but only slightly. You can restore headlights fully with a light wet sanding and polishes with abrasives. The key is you have to finish them down with lighter and lighter abrasives until totally smooth. For example if you start out with Meguiar's 2000 Grade - Unigrit Finishing Sand Paper follow up with the Meguiar's 3000 Grade - Unigrit Finishing Sand Paper. After that you should use a nice light polish that can continue to remove those imperfections like Menzerna PO106FA Nano Polish (Super Finish). This combination will help really get the surface looking more optically clear and feel smooth. If you have any questions please let me know.

But doesn't this make the plastic thinner therefor weaker? You are basically sanding away layers correct? (not arguing just want to understand better)

 

No worries I understand your question and it's a valid concern. The plastic used there is very thick and strong so it can withstand rocks, etc. The process I recommended is meant to be rather gentle believe it or not and will only correct the lightest surface imperfections. In short the amount remove is so nominal it should have virtually no affect on the strength of the plastic. Let me know if you have other questions.

So I tried the stuff on both my 530i and 350z. Didn't do crap for both of them.

But I don't thinks its the products fault. On my bmw it looks like a white cloud of haze all over the cover but carefully looking at them I have no idea what caused it. Looks more from the inside rather than out. And its no condensation.

And on the 350z, the previous headlight owner (have 06 bixenons) told me that the headlights were in a body shop and was covered under a plastic bag while dust was on it. And the moving around caused very fine scratches on the cover.

I want to try the sanding method next but what can I use to protect them in future from uv damage and etc.

 

You can protect them with a quality sealant that you use on your paint or try a product like the 303 Aerospace Protectant. Both will help them after you wet sand and polish the lights.
