About This ✅ Metal preparation before painting is the most important step to ensure a proper finish. Using paint prep products for cleaning metal to remove grease, oil, residue, dirt, grime, or excess rust and etching the metal surface allows any primer, paint, or coating to adhere and create a strong surface bond ✅ Improves Paint Adhesion: Etches metal and leaves a zinc phosphate coating for maximum adhesion, ensuring a strong chemical and mechanical bond between paint and metal surfaces. ✅ Safe and Residue-Free: Water-based and non-flammable, POR-15 Cleaner Degreaser and POR-15 Metal Prep won’t leave harmful residues that can interfere with coating adhesion, unlike other metal prep solutions. ✅ Works with any brand of opaque paint or primer ✅ Recommended to use with POR-15 Rust Preventive Coating, POR-15 Primers, and opaque POR-15 topcoats.
