Richard R. ★★★★★

Finally, a sanding sheet that doesn't load up instantly on wet paint—these kept cutting smoothly through a whole panel. The 9x11 size is perfect for wrapping around my block.

Chloe ★★★★★

The sheets held up perfectly through a full wet-sanding pass on my car’s primer, and the waterproof backing didn’t warp or peel at all. Cut them easily to size with scissors, and they kept a uniform finish without clogging up mid-project.

Timothy ★★★★★

Ran these wet on a patch of primer that kept clogging my old paper, and they cut through smooth without loading up. The 9x11 size is perfect for a block, and they held up through a full panel without tearing.
