Moisture/Rust

Chris asked 4 years ago

I’m painting the interior walls of a building w/ latex. There is about 4 ft. of block walls then channeled steel siding above that. There is foam in between the “channels” and the block. The foam is damp and the steel siding is rusted. Can I caulk w/ paintable silicone then paint w/ metal primer before finishing w/ the latex?
