There may already be a topic which covers this, but I couldn’t locate it.
My 30-gallon barrel SimpleFire has an epoxy-phenolic lining inside and so far has not been affected by heat or moisture and will probably last the rest of my life. Can’t say the same for the accompanying steel 7-gallon filter container with lever-lock lid. I abandoned the earlier plastic filter container due to deterioration from heat. This current 24-guage steel filter container gets damp and sometimes there is a coating of water inside the bottom during the colder half of the year. I’m seeing rust forming on the inside. What is being used to retard or prevent rust in the steel containers and tanks being used in damp areas of your gasifiers or do you just let them rust out and replace them?
