POR-15 Metal Prep provides the best adhesion for POR-15 Rust Preventive
Coating on any metal surface, including aluminum and shiny polished
metal surfaces. Our simple process gently etches metal, creating an
ideal anchor pattern for coatings such as POR-15 Rust Preventive
Coating, while simultaneously leaving a zinc phosphate coating to insure
chemical bonding of paint and steel. Avoid other preps that may leave
harmful residues which prevent proper adhesion. After thoroughly
degreasing your work piece, apply environmentally safe POR-15 Metal Prep
to both neutralize any rust and etch any clean bare metal. This will
allow better adhesion of POR-15 Rust Preventive Coating or any other
coating. POR-15 Metal Prep is not caustic, corrosive, toxic or
flammable.
