I had initially intended on painting my frame with POR15, but decided against it once I realized what it would cost. I instead chose to treat it to the portable sandblaster and twisted wire cup brush to remove most rust. Then an application of "Metal Ready" and 2 coats of Rustoleum Hammered paint with a brush. I had a couple of rattle cans of the same for the hard to reach areas. I had some very bad scale in places but managed to get most down to bare metal.
