What Customers Are Saying
Customers overwhelmingly praise this self-etching primer for exceptional adhesion to bare metal, aluminum, steel, and galvanized surfaces without peeling or flaking. Many highlight its smooth spray pattern, quick drying time, and ability to work on rusted or previously painted metal without extensive prep. The upside-down spray capability and clear nozzle design earn frequent commendation for reaching difficult areas. Reviewers consistently describe application as effortless, with reliable performance across automotive, plumbing, and marine projects. A few report isolated nozzle defects, but most consider this an outstanding, must-have base coat.

Would RecommendI used this to prime an aluminum gasket housing on our tractor. Adhered well and the nozzle remained clear unlike the old style spray cans.

Wrong Product
Would Not RecommendOf the 6 cans of Rust-Oleum Automotive Self Etching Flat Gray Oil-based Spray primer that I ordered, 2 cans were "plain gray primer". Unfortunately, I did not notice until I got home and unpacked the plastic bag of its contents. Went back to the store to correct my order but store did not have 2 additional cans of Rust-Oleum Automotive Self Etching Flat Gray Oil-based Spray primer - which is likely why I was given 2 incorrect cans.

Not Grey
Would RecommendIt’s not grey, it says grey but it’s green. This product only comes in that odd green color, don’t let the description fool you.

Good primer
Would RecommendI purchased this to spray an old truck that I had to repair a lot of rust areas on. I needed something to prime with that would at least make it look better than a back yard job. The primer went on smooth, spray head did not clog like the other brand I tried. It sanded well and gave a good painting surface.
