## Questions & Answers

**Q: How much 600 grit do you use for a 3lb tumbler**
A: Six tablespoons

**Q: why do other brands of 1200 aluminum Oxide cause a glossy finish, but your product doesn't? Why do I need 1500 Grit?**
A: 1200 grit is a final polish, 1500 is not a final polish. You can add Borax soap for a shinny finish. I watched YouTube about it very educational about grits and tumblers.

Great when used with epoxy for a super agressive grip on a handgun. Coat lightly with brownells alumahyde after and you have a bomb proof aggressive grip texture.
