I have some black spots on the rear window of the Suburban. Some are as big as a paper clip and others are smaller. I have tried windex, WD40, graffiti remover, a razor blade and even gasoline, nothing worked. Is there some kind of glass polishing compound that may remove this? Any ideas or advice?

Thanks!!

i have detailed alot of cars and never seen much a razorblade and windex wouldnt take off.that must be some wicked stuff..i will ask the guys at work if they know of anything

Try some Blue Magic polish. I used it on my side mirrors, which were pretty filthy, and now they look like new. Windex wouldn't clean them good enough.

Very fine steel wool and acetone, worth a shot..

This is some stubborn stuff... maybe I'll mix acetone with some blue magic polish and scrub with steel wool. I was sure the gas would take it off. You know the scuff marks black shoes leave on a tile floor? That is what they look like.

BTW... just kidding on mixing the polish and acetone...hehe
