Re: Dealing with Rust
Most effective method for dealing with rust is to remove the paint and then treat it with a phosphoric acid solution. There are phosphoric acid rust removers with zinc that are effective especially in welded seams . It dissolves the rust and leaves his Zinc film. Panels treated like this they can stay indoors for a year without re rusting. Two coats of a aluminum pigmented permanent rust sealer Do not use black follow it up with any kind of primer you want over that and then your color. By utilizing a phosphoric acid solution and top coating with an airtight seal you have done everything humanely possible to prevent rust.
