it's a good go to for mid range grit sandpaper. i used it to prep and rework a fiberglass speaker enclosure that I made for my Tacoma. Later layers of filler require wet sand to get the surface smooth and ready for paint. This paper held up to the sanding and the water. I was able to use one sheet for considerably longer than I had expected.

always good quality sandpaper from this company. I wish I could say the same about the service from walmart these days. They could care less about any of their customers.
