Hey Tony! I’m not sure there is any one great solution. Some believe that a rubberized coating is worse than just automotive paint because it can cause more condensation underneath leading to more rust. And there are some who have used it with good success. I personally think you’ll be dealing with rust no matter what, unless you’re willing to fork out the money to have it stripped to bare metal inside and out, have bad metal cut out and replaced, and then painted with an industrial coating.
