I'm thinking about Making an UDS or getting a WSM. So my next door neighbor/Uncle has some steal drums for sale $8 We set one aside that looks like it stored some type of water based paint in it. They seem to be made of a rather thick gauge steel, and had a red lining on the inside that would need to be removed. Here is a picture of the top of the drum. So if I clean out the inside and torch off the paint/liner inside and out would it be safe to turn into a smoker? If not he has some older thinner ones, they have rust on them and used to hold Butanone http://en.wikipedia.org/wiki/Butanone and don't appear to have any lining on the inside but is most likely just clear. I don't have a torch to remove the paint should I one or will a pallet fire in the drum do a good job?
