My brother found some 55 gallon drums that are new never used open lid. The man he purchased it from told him the lids were galvanized but I have not seen them yet. If they were galvanized would it be safe to paint both sides of it with high heat paint and use or should the lid not be used at all. Also is there a way to tell if it is galvanized just by looking at it. For his build we were looking into getting a kettle lid from big lots anyway but I have not done any mesurements for him to see if it would fit. Any advice would be awesome.
