All head lights can work with sandpaper?

Re: Help

Sorry, are you asking how to correct badly oxidized headlights by wet sanding them first? Or do you have a different question or situation?

Re: Help

yes, car mileage 100k miles, the headlights are covered with film, strongly oxidized, polish m105 does not work, how correctly to do?

Re: Help

There was a link with a Supra here on the forum that showed a really good way of cleaning up car lenses. What MY exp shows that if it is bad enough that most wet sand and by stepping down progressivly to a finer grit and buffing out w/ a Wool pad and Plastic X got some spectacular results. IF I can find the link. I will post it.

I used to own a car that was pretty bad but sold it but IF I can find it, maybe I would do current write-up.

Great Write-Up.

Also mind you that from what I understand that this is only for plastic type surfaces. When you start to get into stuff like glass, its a whole nother kettle of fish.

Not that I expect that to be an issue with head lights but the question comes up on getting scratches out of glass.

Great Write-Up.

Yes it is. For very badly oxidized lights we highly recommend at least 1500 grit followed by 3000 grit before final polishing. That final polishing can be with PlastX or M105 as either will remove the final 3000 grit sanding marks with ease.

Now, if the headlights are really bad you can start with even more aggressive sand paper than 1500. Our pro headlight and spot repair kit comes with 320 grit all the way up to 3000 grit - what you use to start depends on how bad the lenses are, but you should always work up to the finest grit before final polishing.
