I'm going to remove as much rust as I can grinding back to bare metal where possible, de-grease then apply the corrosion sealer then a couple of coats of the etch primer followed by a light Grey top coat, as this is probably less porous than a primer to put a wax oil stone chip on top of,
does all this sound OK or is it a bit overkill, also is one liberal coat of the mipa corrosion sealer enough?
