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

Basic stuff that just works
Bought this for my tiny dorm “tool kit” because my old beater car started losing compression on one cylinder. Borrowed a friends garage spot, pulled the head off between classes, and used this valve grinding compound with a cheap suction stick. It’s thick and gritty in a good way, so I could feel it cutting while i spun the valves. After a few rounds the seats looked way cleaner and more even. Clean up was easy with brake cleaner and rags. The tube is small but theres plenty for a couple engines. The part that really made me glad was hearing that engine fire up smoother on the first start.
