Review: good - Good product. Great price
Review: Permatex 80037 valve grinding compound works great for engine valve lapping ⚙️ - I used this 3 oz white Permatex 80037 valve grinding compound during my small engine rebuild. It’s perfect for hand lapping valves to clean up minor surface flaws, carbon buildup and light corrosion on valve seats. The abrasive paste spreads easily and maintains consistent grit while grinding. After lapping, I got clean, even sealing marks around every valve face. It works on automotive, motorcycle and marine engines, and even handles chromium components. The tube seals well so the compound won’t dry out quickly between repair jobs. A small amount goes a long way; this tube is enough for multiple engine rebuilds. Way better than generic off-brand lapping paste. If you do your own valve work, this trusted Permatex grinding compound is a must-have in your shop. Highly recommend

## Questions & Answers

**Q: What is the grit of this compound**
A: The back of the 3 oz. tube package (80037) says:

NOTE: there are 4 grit sizes in one application of the valve grinding compound: 220, 180, 150, and 120.  It starts as a course [sic] 120 grit then grinds down to a fine 220 grit.  To thin the compound, add a few drops of water.

**Q: What is the grit of this compound? Is this a total of 12 3-oz tubes, equaling 36 oz of compound? Thanks.**
A: I inquired with Permatex Technical Services: Both 80036 & 80037 are "...a mixture of four grits – 120, 150, 180, 220. As you begin using the compound it starts off as 120 and as you work it it ends up as 220." The difference between 36 & 37 is 1.5 and 3.0 oz tubes.

**Q: what material is this made with? most lapping compounds are made of either silica carbide, or diamond powder**
A: Silicon Carbide

**Q: Is this applicable for pet clipper blades, stainless steel, I need have a very slight concave?**
A: I don't know if it will work on the clippers . I use it on car engine valves and it does a great job on them .
