Ok, I realize most woodworkers don't think much about sandpaper. I never did until I recently bought a pack of 3M Sandblaster sandpaper. What a difference from the generic crap I used to buy. It really removes material and will not clog up. With my old sandpaper I refused to use my sanding blocks because it clogged so quickly that I spent more time changing the paper than sanding. Does anyone else have a favorite brand of sandpaper?
