Review on 🔪 3M Cubitron II Hookit Clean Sanding Film Disc 775L - 220+ Grit Vacuum Sanding Disc - Multipurpose Hook and Loop Attachment - Ideal for Metal, Composites, and Fiberglass Surfaces - 5" Disc Size by Ryan Whatley

Cubitron outperforms a standard sandpaper disc by at least 4 or 5 to 1. I have a Bosch sander and am not just a Cubitron longer than paper discs , but I also see a lot less stickiness or buildup. I have used 80, 120, 180 and 220 grit and they are all great. I will never go back to the old paper sanding disc. It also takes less sanding time to achieve the same finish. Either way, you really need to keep your grinder running and making sure it circles or you're applying too much pressure. You do this and your grind will be enjoyable. I'm amazed at how long the cubitron lasts, which makes it worth the extra money.
