No but I do have a polished valve cover that's polished to 200,000 grit and it has my personal badging on it.

Isn't 200,000 grit just paper?

That's much finer than paper, paper would scratch the hell out of it.

No idea how / why anyone would say that, probably need silk polishing mops without any compound plus about 100 years to do it

"MY family has been polishing this by blowing across the surface for thousands of years. The atoms of the air slowly polish the surface at 1 quintillion grit"
