Rust Issue

Try Por 15. It really worked on my Pinzgauer 4x4.

""Since POR-15 actually bonds to metal, the underlying surface does not have to be sanded before application. As long as loose and flaking rust are removed from the surface, an application of POR-15 will not only cover up the rust and prevent it from spreading, but will also strengthen the underlying metal and seal holes by forming its own membrane.""
