Review on Ultimate Flexibility with 🛠️ Motor Guard SB 1 Sanding Tool by Brian Kumar

Love it. The material is just right - malleable enough to be used on light contours, but hard enough to create a flat surface. The hole structure seems to do a really good job of removing material. My only criticism is that the block doesn't appear to be solvent proof. I like naphtha or mineral spirits for wet grinding and have noticed some block degradation. But water works.
