Re: tank coating
Doing bondo work these days The metal is so then. Especially on doors if we did not reskin them. I had to put Fiberglass resin [with the fibers] on the back side . Then I could block sand the door with out making a wave in my bondo work on the outside.
When a guy can do metal work for the most part and only need a bit O primer that's a true body man!
Still gotta have a since of humor.
