Is sanding bad for headlights?



I've been learning to do work on headlights by wet sanding and compound followed by UV protectant. I have been getting great results. However, I ran across this on a search and it got me wondering if I am messing up the headlights.

THE TRUTH ABOUT HEADLIGHT CLEANERS | eBay

Is this info correct or hype?

Thanks!

OMG. they say to use tooth paste!
I'm out!

Stupid stuff.

When you sand the UV off you replace it.
When you sand plastic you polish it.

The only thing I know of that will actually destroy Acrylic is ISA.

Don't listen to this kind of crap. You obviously know what your doing so why even ask.

Toothpaste was actually the old-school thing to use on acrylic.

+1 tootpaste does in fact work. Is it the best abrasive generally no but yea it works.

The ebayer said If it comes in a can, tube, cream, paste, or powder it is not non abrasive. Non abrasives are pure liquid. This flat out isn't correct but he is trying to say sanding the lens removes the UV protection and it has to be replaced. Commonsense says we knew that.

OP just keep on doing what you're doing. He's selling what he thinks is a better mouse trap.

I was saying that was for acrylic, what we used to call Lucite. Headlights are polycarbonate/Lexan, I dunno if that makes a difference as far as polishing the bare plastic, but knowing how hard it is to sand off oxidized UV coating, I know toothpaste isn't going to do much to it.

I know that deep polishing will indeed remove any UV coating and lenses will get cloudy quite quickly without adding some protection. I have not heard the absolute best product to protect afterwards however ....

What about Opti Lens Scott? Absolutely the best product for protection.

Thanks for the feedback, everyone. Figured I'd get this sorted out here.

haven't used it nor seen it in any long term results. I do have faith in Dr. G however. I have heard mixed results with Opti-coat and Spar Urethane. If this is the product, then great !!
