Handy little valve grinding compound works well for my repairs
Wanted to try this out on my motorcycle valves, and it has made a noticeable difference. i appreciate that it’s a small 3 oz. size, so it doesn't take up much space in the toolbox. the white color is easy to see during application, which is helpful. used it during a weekend project, and the results were satisfying. it’s not too gritty but just enough to do the job smoothly. glad i picked this up; it’s been a handy addition for maintaining my bike. 😊

Works well for my hand valve grinding on some old 1600 beetle heads. Gets nice and fine after a minuit of grinding Put a bit on, spin and tap. Clean. Inspect, reapply and go till happy

Followed the instructions I found online (removing the wheel covers, swapping the gear situation and putting it back together to reverse the rotation of the rotary mower) Sharpens nicely though I do recommend you use gloves as it does say its a carcinogen and I understand this compound is a bunch of tiny shards of metal, please protect your fingers, you only have one set of hands. I was under the impression that this was a powder that needed to be mixed with water to use (as it suggested a mouth mask and eye protection) but its already a wet paste ready to be smeared on the blade so not much risk of inhaling unless you leave it to dry out. Idk about other uses but for sharpening a rotary blade push mower (non-gas) it works perfectly
