JB WELD JB Weld Valve Grinder is a water-based odorless and abrasive paste designed to aid in valve grinding and lapping operations on engines to remove burrs, surface defects, deposits and corrosion. The paste combines 4 grit sizes so that one application begins as a coarse 120 grit, then grinds down to 150, 180, and then a fine 200 grit for a fast and smooth finish.
