I use oxy-propane instead of oxy-acetylene for my cutting torch. My shop space is small, so I don’t store it inside. For a few years, I’ve had it under a new plastic trash can, but it looks bad. I finally made a cover for it, from scrounged metal a friend had left over from a job. The winds always blow north or south, so it only needs the side walls. It rained a few hours after I made it, so it’s already been tested.
