1 Gallon (3.8 Liters) Can of Custom Shop Premium Self-Etching Acid Etch Primer. Black primer color. It etches and primes bare, rust-free metal in just one step.
Premium Self-Etching Acid Etch Primer is a ready-to-spray, self-etching primer with tremendous adhesion and flexibility properties. It provides excellent adhesion to the following properly prepared substrates: steel, aluminum, fiberglass, previously painted surfaces, wood, and some plastics. It's a super primer with anti-corrosive properties, which makes it ideal for use over bare metals such as aluminum and steel. It's the perfect primer for fleet and OEM manufacturers. This coating is fast drying and is sandable after 60 minutes. It also improves color holdout, gloss retention, and has excellent inter-coat adhesion. Ideal for use on properly prepared truck beds before the application of truck bed liner coatings. This primer works excellent under all major brands of truck bed liner coatings like Custom Coat, UPOL Raptor, and Gator Guard.
Awesome laying down fast drying and hard as nails.
The 1922 Hudson in photo is a single coat of Self Etching Primer.
Unfortunately it needs MEK for clean up which is hard to find, expensive and very nasty to work with. But, for sticking to untreated aluminum, it works.
Excellent product great bonding to bar aluminum flowed nice and smooth
