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

This small tub helped rescue my old motorcycle valves
These days I’m trying to stretch the life of my old Yamaha instead of replacing it, so I grabbed this valve grinding compound for a top-end refresh. Texture feels gritty but controlled, and it cuts nicely without chewing things up. I could feel the valves seating better as I worked, which was oddly satisfying 😅. Tube size is fine for a home garage, but I do wish the lid sealed tighter. I have a messy workbench in my home studio and it loves to pick up dust. I also found it a bit annoying to clean completely off the parts, so keep some extra rags and cleaner nearby. For the price though, I’m glad I used this instead of paying a shop.

Excellent product.
Worked well on my Subaru valves. There is enough in the tube to last me the rest of my life.

Handy compound for our gym workshop
. I grabbed it to freshen up an old air compressor valve that powers our lifting platform cleaners. I smear a thin ring on the valve seat, spin it with a simple suction tool, wipe, then check the seal. Took me about twenty minutes and the compressor stopped leaking and cycling nonstop. That alone made me glad I bought it. The tube is small but it goes a long way because you only need a dab each time. Texture is gritty but spreads smooth. Cap screws on tight so it has not dried out in the cabinet.
