I bought a set of Ross pistons from a FB seller that arrived a while back. I opened the box to find a few concerns that I would like more experienced builders to review. About 4 of the pistons show what appears to be light corrosion of the aluminum which can be felt if you drag your fingernail over the areas. It seems to clean up easy enough with a brillow pad but before I move any further with these I would like your input... here is a link to the part number of the pistons:
