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.

Could have given this a 10 if possible

 Would Recommend

Was refurbishing rusted shelving and toolboxes, bought this primer on friend's recommendation. Where has this been all my painting life?!? Wired-brushed and sanded to remove much deep flaking rust before using primer, though not all of the rust. Goes on evenly, dries quickly leaving a bonded matte surface that fills in and hides minor imperfections. Excellent prep for finish coats.
