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.

Great self etching paint

Would Recommend

Been renovating an old Coleman crawdad boat. Aluminum poles were pretty scuffed. This paint adhered and filled spots then used a silver paint over top. Worked great.

Would not spray

Would Not Recommend

I purchased this can of self etching primer, and shook it for a couple of minutes, and tried to use it and it would not spray anything out. Waste of money because it is now too late to return it. Didn’t even get a drop out of it.
