L58 Lapping Compound, 4oz (113 g)

This is a lapping compound made with a natural abrasive. It may be safely used on brass without the worry of any abrasive residue being left behind. The extremely fine grit will polish the roughness out of valve casings or tuning slides for smooth action. Especially useful when used with the N58 Valve Mandrels, the N28 Valve sleeves or the N98 Valve Lapping Machine. The Lapping Compound should be cleaned from the surface using Z10 Cold Cleaner. 800 grit leaves nice Monel appearing finish.
