3M’s consumer abrasives are also remarkably good. Not only are they more effective during use, but they last longer as well, with a much later falloff in abrasion quality. In fact, they last so long that their price (nearly double the price per pad in my case) easily justifies itself. I have no idea what kind of black magic makes it possible but I’m so glad I gave them a try.
