[QUOTE="Johnny, post: 379431, member: 13599"] Ospho is not designed to REMOVE corrosion - or make a smooth paintable surface. It is only designed to NEUTRALIZE the rust or corrosion so after a suitable primer is applied and after it dries/cures, it forms a moisture tight barrier between the metal and the topcoat of paint. The topcoat will be the one that actually provides the protection to "retard" any future rust or corrosion. You are on the right track to physically and mechanically remove any surface corrosion first - - - [b]then[/b], use the Ospho prior to applying your primer to actually get into the pores of the metal and completely kill any corrosive salts.
