Years ago, JD recommended this when they were out of stock on the 3M paper I wanted. I'll never go back to 3M or any other brand.
This stuff cuts like an edge tool, won't clog and lasts many times longer than other brands. I can do a 320 grit finish sanding on my 30 foot topsides using less than two sheets! I almost never use my power sander anymore.
Use the next finest grit, as compared to 3M, because the cut is agressive.
