Norton 3X - Good stuff
Square2Round,
I use everything from 100 to 400. I avoid <100. Since it stays so sharp, it cuts deep grooves that I have problems sanding out later.
I've actually all but stopped powersanding as I can handsand with the sheets in 1/2 the time/heat (usually). I'm only using up my ALOX new waves discs becuase I really don't want to throw them away. I'd LOVE to find velcro backed seeded ceramic gel sandpaper (like norton) as it'd REALLY cut down on my sanding time.
Bottom line, after trying it, it is the only sandpaper I'll buy (3M also sells SG sand paper under the sandblaster name, I still think the norton is a little better)
