Por-15 40201 "Metal Prep" Rust Neutralizer and Pre-Primer (Gallon)

Provides the best adhesion for POR-15 on any surface, including aluminum and new metal surfaces.
Our simple one-step process gently etches metal, creating ideal adhesion for POR-15 coatings and others, while simultaneously leaving a protective zinc phosphate film.
Other preps may leave harmful residues that prevent proper adhesion of POR-15 or other coatings.
After thoroughly degreasing your work piece, apply Metal Prep to both neutralize any rust and etch any clean bare metal.
