Hey Guys, been reading this thread for weeks now. I finally found a food grade drum with no epoxy inside, and after bringing it home I noticed it had a gold tint on the inside, almost like a clear coat. It originally held concentrated lemon juice. After grinding it a bit, it comes off as easy as the paint outside, but obviously a pain. Will the first burns take care of this? I'm looking into getting it sand blasted by a buddy of mine, but was wondering is this why everyone says the first burn is so important? Sorry if it's on here somewhere I haven't seen it.
