The first drum I burned out I warped the lids as well. The 2nd time around, I put the lid over the barrel for a few 4 or 5 minutes as soon as the paint started to turn, I took it off for 10 minutes then put the other side to the flames until the paint started to turn.
After cooled, wire brush and wire wheel easily did the rest with no warp. This is a lesson we all learn the hard way.
