POR-15 Rust Preventative can be sprayed or brushed on to provide a rock hard, yet flexible, non-porous coating that will not shrink, peel, or crack. It is totally resistant to road salt, petrol, battery acid, etc., and actually dries harder in humid damp conditions. Ideal for suspension and chassis protection, and you can apply a topcoat of any finishing paint. This is protection you can count on. Metal surfaces should be treated first with POR15 Cleaner Degreaser, then use POR-15 Metal Prep to dissolve rust, etch the metal and leave a Zinc Phosphate for better adhesion of the paint. Use the POR-15 Solvent to thin (if required) and to clean brushes.
