Dished out Shapton Ceramic Stone
My 8000 grit Shapton stone is dished in the middle. I spent about 15 -20 mins with the fine powder trying to flatten it. Doesn’t seem like I’m getting any where. Can I use the medium grit followed with the fine powder. I assume using the medium grit will cause scratches on the stone. Will the fine grit get rid of the scratches?
