I have started restoring my Camaro from the underside up. There is some rust on portions that I have to deal with. Every time I think I have a plan I read about another one of your products and get confused where to start. You have Rust Converter, Rust Encapsulator, Rust Disolver and Rust Disolver Gel. Do I use only one or all of theml, only some and in what sequence. Please help me get started.
