CERIUM OXIDE 250

It's very useful to remove light scratches and swirl marks. Night drivability has improved a lot. It's better to try this before changing the windshield. I think apart from abrasives, it also chemicaly reacts with glass to smoothen the surface.

Waste of money

Good item but difficult for inexperienced person to use

Removes minor watermarks with hand buffing and major ones require a polisher or variable speed angle grinder. FYI I have used DeWalt 4118 . Results were satisfactory as instead of watermarks I got few scratches using it.

Works good on glass best more removing the small scratches and glare

Not working. Don't buy this

Product works. Yes, it works sufficiently good. I own a 10 year old car of which glass hasn't been polished since the purchase & there were many scratches on it. Also, while driving in night, there used to be circles of light from opposite lane's vehicles, when it fell upon the front glass. Those circles (whirls) were completely removed after I rubbed this polishing compound using a microfiber (and a little water) for just 15 minutes. One out of five stars is lessened because the plastic container of the item was leaked inside the cardboard box, though not so much was leaked. Thanks for reading till the end.
