Review on 🛠️ DRILLPRO 70Pcs Sanding Discs Set: 2 inch Quick Change Discs for Die Grinder, Surface Conditioning, Strip, Grind, Polish, Rust Paint Removal (Updated) by Sam Bhushan

For general surface preparation and preparation of specific areas. Also as a cleaner/removal of old gaskets and seals prior to reassembly and sealing of automotive engine surfaces. I'm used to the 3m line of products. It's not 3M quality, but at a discounted price, the price isn't that bad. does the job. They shed a lot of cushion and support material as they wear out and dump that waste throughout the job. Not good for anything internal to an engine that isn't rebuilt and cleaned afterwards. But good in the breakdown phases. They also tend to clog and load any scattered paper grids much quicker than the more expensive brands. You get what you pay for
