POR-15 painting requires prep work and makes a mess unless you have some sort of professional set up to do the work, plus if not done right can cause more harm then good. You are better off buying about 6-8 cans of Fluid Film and pressure washing the entire under carriage, let it dry, then coat the entire undercarriage before the winter with this stuff. Fluid film works on any existing oxidation, as well as protects your undercarraige from future corrossion. Do this ritual annually and your undercarriage will stay looking virtually new.
