I rebuilt my Tudor about 31 years ago, but I didn't do anything to the underside of the body in terms of paint or rust prevention. I noticed the last time I was under it that the floor pans are looking pretty rusty. I could just paint them over with POR 15, but that stuff is not easy to work with, especially upside down and painting over your head.
Can anyone suggest a way to address this rust short of removing the body or hours laying on my back with a steel wire brush and the ensuing prep? Some easy, lazy, old-man solution?
