You don't have to remove all rust on metal before painting. Rusted metal is converted overnight into a black, rust-retarding paintable surface after using Jasco Prep and Primer. Converting rust from iron oxide to iron phosphate, this product prepares the metal surface for paint or auto body filler to have maximum adhesion and longer life. After it is applied, degrees of color change may vary from metal to metal but usually will turn to a whitish-gray powder, and then black, to show a chemical reaction occurred.
- Converts rusted metal into a black, rust-retarding paintable surface
- Great for use on galvanized metals like bicycles, autos, gates, chairs, roofs, gutters, trucks, railings, tables and fences
- Non-rusted, galvanized and new metal surfaces of ferrous or aluminum can be quickly prepared for painting as Prep & Primer can be rinsed off and dried after 30 minutes
