FredT:That tank is hot dipped, with adhesion failure at the stamp. Wire brush the stamp and ZRC coat the area a couple of times.

Thanks Fred... That's what I thought... I'm supprised to see that the coating is that thick. Should I do it before or after hydro? or does it matter? It's actually cleaning up really nicely... all the white spots are superficial and come off with a little elbow grease
