OK, these are the drums i got for my UDS build. They were blue with white lids, that i had sandblasted. They were food grade, and had original labels on them that were for Corn Syrup.
My stupid n00b question is, how can i tell if these are galvanized steel? I just read that some barrels are actually galvanized steel, and are not safe to use for a UDS. How can i tell?
EDIT--I have also read that sandblasting removes the galvanized coating, so i should be good, yes?
