Where do you purchase your sandpaper?
I've been getting sheet packs of 3M and Norton papers at a large orange store in #80 throught #600. I think I'm correct that finding as grit sizes get finer, the paper may change from aluminum oxide to silicone carbide, (or visa-versa.) The #600 paper is black wet/dry, and the lesser papers, such as #400, #320, are 3M yellow backed paper. The #220 and below are, I assume standard aluminum oxide.
I did a search here on sanding and read through dozens of threads on methods and what types of paper everyone likes. But not many spoke of their sources. Maybe that's to avoid appearing like adds for stores. I could research prices of on-line outlets and compare with my local home improvement centers, but no - that's what this forum is for. Besides, I'm lazy. I hope this sparks some good replies.
