Review on 🪚 POWERT E C 110290 6-Inch Self-Adhesive Sanding Disk with 80 Grit Aluminum Oxide, Pack of 10 by Mark Turner

I thought the first flying saucer was my mistake. After thoroughly cleaning the aluminum plate with solvent, the discs still do not stick. When I use a disc sander everything is fine. But when I use a grinder to use the belt, the disc eventually flies off by itself. I often use a belt on my grinder and have given up. When the disc falls off, my sander works like a belt sander until I desperately need a disc sander. I'm so tired of applying (or reapplying) these miserable grinding wheels. I think I could buy spray glue. But while I'm at it, I'll probably buy some new grinding wheels.
