I removed my cylinders for a good rebuild. And while they were off me and ds650_rAcEr Stripped the cylinders of the black paint....sanded them down the best we could...color sanded...then steel wooled them and finally the polish....we used Never Dull....it worked great....I needed some 3M Polish though...that stuff is great! The finsished product is very nice. Not spectactular but very very nice!
