Interesting on the liner... I wonder how many different things these are coated with? I think you can see it worked on mine from the picture. Did you coat the crap out of it and really let it foam up? I bet I used half a can or so on the lid. Let that shiz totally foam up and sit for awhile. Then I scrubbed with like a green scrubby. Who knows what all different things these barrels are painted with....
