Glass Polish 3 inch (75mm) 320 Grit Pack of 10 Silicon Carbide Sanding Disc - Wet and Dry Abrasive Discs - P320 - GP13303

Good product.

Junk. Verry little grit

I like it.

These are pretty coarse. They will remove heavy scratches but leave swirl marks that will require additional work to remove. Having worked with them, I prefer to skip using these and just start with the fine disks. The fine disks don't cut as much and take more time but don't require as much post polishing.

Discs work as advertised, but don't last as long as I expected, so doing a large badly etched glass can get expensive; but still substantially less than replacing the glass.

Used to take haze down from the coarse disks. These do not last long at all. I used most of them just fixing a few small scratches. At a dollar a disk I expected to get more use out of them.
