I liked the idea D. But our buddy Big Block had it let go on the car he is working on. I have used after cleaning and treating rust with vinegar and water treatment. Then cleaned with fresh water. Wipe it down and dry completely. Then applied the Rust Reformer form Rust Oleum. It come's in a spray can. Let it dry for 24 hour's then put my epoxy on. Then applied what ever other paint or clear coat I wanted on. So far so good. I did get East Woods Rust reforming in a gallon jug. after cleaning all frame rail's and inner structure sprayed that stuff in every thing let dray a few day's then epoxy painted every thing. I have done all I could to prevent the rust monster from coming back. That is what take's so darn long on this car to get where I am at now. By buying The East Wood bed liner gun with extensions one has a straight nozzle and the other has 360 degree fan and straight spray out the end could get into places not able to reach any other way. Like frame rails-rocker's- and interior framing. This car should last another 50 years or so. I hope. Russ
