Ok. If this is a repost then forgive me. I'm not doing too well with the search thing. I noticed some rust underneath my 1983 Jeep CJ7. It's not major but I want to prevent it if possible. I found some stuff called "Rust Killer" It is a coating that neutralizes the rust and dries to be a rust preventor. Does anyone know of anything better. I have heard of POR15 but it sounds labor intensive but I don't know much more than that. Thanks for the help in advance.
