I had a 55gal steel barrel that I was burning out for my UDS build. This food grade barrel had a brown painted inside which I am assuming was the dreaded liner. I picked up a mixture of hardwood from a pile of broken pallets & started my fire. After about 4-5 hours of burning I looked inside & had about one foot deep of hot coals. The next day I came back out & noticed the only about half of the outside paint had burned off & about 90% of the liner. Under the liner was another layer of blue paint. I installed a paint stripping disk on my angle grinder & started trying to dress up the inside to see what I had. What I though was soot on the inside was actually still liner residue with a blue paint layer under it.
My questions are:
1 - Is this common for a burning out a barrel with a liner?
2 - Do lined barrels take more than one burn out? In other words, if I do another burn out or two, will the other layers of paint come out?
I'm actually asking this for my next barrel because on more inspection I noticed this barrel had several rusted pinholes in the bottom so Im making a trash barrel out of this one.
