So my local drum reconditioner turned out to be a dud. When I finally picked up my drum (which at $40 was no great bargain anyway, but at least I figured I could build) and opened it up, there was a liner. Grrrr. Back to square one. So yesterday I came across an add on tradio for some open head drums that a farmer has. There is a read liner or some sort of paint on the inside but it is mostly peeled off already and I'll have no trouble getting the rest off with a wire wheel. However there is some rust on the barrel. Nothing terrible and certainly no structural issues. Mostly rusty around the lip. Is this okay? Please tell me I can still use this drum. Lie to me if you have to. Is there anything special I should do to it to keep it from rusting further? Besides painting the outside that is . . . Thanks in advance!
