Rant: I was dead wrong about those cheap 3M sanding discs on Amazon

For the longest time I thought those no-name discs from China were just as good as the name brand stuff. A guy at my shop in Phoenix swore by them, so I bought a 50-pack for around $12. First panel I tried them on, they loaded up with paint after two passes and left deep scratches I had to buff out. I went back to the regular 3M ones and finished the whole job without swapping discs once. Has anyone else had bad luck with those bulk packs, or did I just get a dud batch?

Yeah that's the thing with cheap discs, they can leave behind the grit particles in the surface that cause those fine scratches you don't see until the light hits it right. I heard from a painter that some of those no-name brands use recycled sand material that breaks down unevenly too.

Man, I used to be totally on that same train. I grabbed a big pack of those cheap ones thinking I was being smart with my money. But after watching them gum up on some old paint and having to switch discs every five minutes, I realized it's just not worth the hassle. The name brand stuff might cost more but it saves you time and a lot of cussing in the long run.
