Re: NOS GM Camshafts with rust on Journal Surface
Yeah, definitely wet sand with WD-40 or similar light oil. Clean up, buff with crocus cloth and clean again. Need the surface polished. Random small spots/micro-pits are ok. I'd be worried about if full width of journal surface is scarred with pits you could feel with your nail. Hard to tell in the pics.
