2000 grit sand paper with 30 weight motor oil.
Do it with the cylinder horizontal so nothing ends up between the piston and cylinder wall.
Wipe it dry with a clean paper towel then apply a thin coat of clean motor oil.
I have super fine steel wool the finest I could get it is 0000 idk if u know what I mean by that.
Can I use that and some motor oil with it on block?
Will be doing it today If all is good with that..
