Safe & Easy To Use Removes Surface Rust In Minutes! Coats Metal With Zinc Phosphate Provides Perfect Base For All Paints Gives Better Welding Conductivity PREP & READY provides the best adhesion for POR-15 on any metal surface, including aluminum and shiny polished metal surfaces. This simple process gently etches metal, creating an ideal anchor pattern for coatings such as POR-15?, while simultaneously leaving a zinc phosphate coating to insure chemical bonding of paint andsteel. PREP & READY Features Easy to use - one step process No harmful residues Is reuseable Removes surface rust in minutes Coats metal with zinc phosphate Insures perfect paint adhesion Provides perfect base for all paints Gives better welding conductivity. Avoid other preps that may leave harmful residues which prevent proper adhesion. After thoroughly degreasing your work piece, apply environmentally safe PREP & READY to both neutralize any rust and etch any clean bare metal. This will allow better adhesion of POR-15 or any other paint. PREP & READY is not caustic, corrosive, toxic or flammable.
