I was looking at sandpaper with grits above 4,000, and found micro mesh with up to 12,000 grit. They even have it in 5" velcro discs.


However, then I found this:

Does any one know if it's true, that they play with the figures like this? It appears their 12k grit is about equal to our 4k, which I can get at auto stores.

Thanks.
