First i started off with sanding the metal down intill the sliders were a little bit shinny. After sanding I cleaned them with Acetone. Then I primed with two coats of gray primer Finally I painted them with Rustoleum Hammered spray paint.
did the same thing but I used ethyl alcohol to clean the metal and I didn't sand it, hopefully it'll last... how mnay coats of the rustoleum did you put?
