How to rejuvenate stone chipped / scratched headlights.

As I'd taken off my old top cowl to replace it with a new one, I took the opportunity to rejuvenate my original headlights.

The previous owner had tinted these blue - and over the years the lights had gotten a little stone chipped too.



First I wet sanded with 320 grit paper, to get the blue tint off and make sure the stone chips were all smoothed out.

Then I went to 1000 grit wet sanding, making sure I'd gotten all the coarse scratches out.

This is what it looked like at this point:



Next I went to 2000 grit, but had difficulty making progress fast, so I got my Porter Cable Polisher & glued a 6 inch round piece of 2000 grit paper to a polishing towel...

Much easier!

Looked like this after around 15 minutes (Per headlight):



Then I took another polishing towel designed for use with the polisher, sprayed some glue on it and attached a 4000 grit 6 inch disc. This was to take the finest scratches out. Took around 25 minutes per headlight.

After that, I used a foam pad to polish with rubbing compound, then another foam pad to finish with a cleaner polish.

This is the final result:

This technique also works well for dulled / yellowed car headlights.

Best use a polishing machine such as a Porter Cable Polisher - or you'll burn a lot of time & elbow grease!

Thanks Makis.

Thee trick is in using really fine grade wet & dry paper - to get all the little scratches out, then polishing a lot afterwards. You can't burn plastic with an orbital polisher, so go hard on it...

BTW, still no news from Moriwaki on your parts (& your mufflers are safely here - ready to send). I'll ask my guy tommorow what's happening with Moriwaki...

Since the PC polishers cost $$, I'll also say that Harbor Freight makes a nice polisher that I've used on my truck with great success. Haven't used it on headlights for this kind of work, but it has performed will on paint. I think I paid like $40 for mine.

That is an awesome job you did on those headlights Stig.
They really turned out nice, looks just like they came from the showroom floor !
Good write up on steps to restore them. I have used the same methods to restore many headlights to their former glory.
I see this thread as sticky material for sure.
Well done stigmeister

Very impressed, I don't think I have ever seen sand paper finer than 1200 grit though. And I love that bike. Best scheme there is bar none

Auto paint supply store will have them all the way to 10,000 grit or more.

Do the headlights look just as good as when you originally did them?
Did you have to seal the lights when you had done them?
