Etches Metal and Leaves a Zinc Phosphate Coating

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. It creates the perfect anchor pattern for any topcoat, especially the incredible POR-15 Rust Preventive Coating.

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.
