Prep & Primer

You no longer have to remove all the rust before painting! Rusted metal is converted overnight into a rust-retarding paintable surface after using Prep & Primer. Converting rust from ferrous iron to iron phosphate, this product prepares the metal surface for paint or auto body filler to achieve maximum adhesion and longer life. After it is applied, it will turn from a whitish-gray powder to black, showing a chemical reaction occurred.
