Product Details

SEM 39673 Self-Etching Primer is a professional-grade, single-step coating designed to provide superior adhesion to bare metal substrates. This black primer chemically etches the surface while priming in one application, eliminating the need for separate etching and priming steps. The self-etching formula is ideal for automotive, marine, and industrial applications where maximum paint adhesion is critical.

Key Features:

  • Self-etching formula bonds directly to bare metal, aluminum, and galvanized surfaces
  • Promotes excellent adhesion for topcoats and reduces paint failure
  • Fast-drying formula allows for quick recoating
  • Black color provides optimal coverage under dark topcoats
  • 20 oz aerosol can for easy application and precise control
  • Resists corrosion and provides long-lasting protection
  • Can be topcoated with most automotive paints and coatings

This primer is essential for bare metal preparation in automotive restoration, collision repair, and custom painting projects. The self-etching action creates a strong mechanical bond that helps prevent peeling and flaking, making it an ideal foundation for high-quality paint finishes.

Quality parts at a good price. Fast delivery. Only reason I did not give five stars was that the parts were not packed securely, and the one package broke open and lost one of the nuts that go to the muffler clamp. Now I have to buy another muffler clamp from the auto parts store. Besides that I was very satisfied with my experience.

Helmet is as described and fits fine, however, it's so huge I cannot use it in the car as intended. Some reviews call it "Marvin the Martian" looking. This is generous. It's more like Marvin the Martian on steroids. Will need to return and look locally for a helmet.

Nice and fast, clear and easy to read if this is the part I want, and if it will fit my car or NOT.

Everything went according to plan. It was great!

The best price on what I was looking for and fairly fast to get it shipped out considering it was drop shipped directly from the manufacturer. Autoplicity has a huge selection and I will definitely be back when ever I need other automotive parts.

Very smooth

Nice site. Checked you folks against RockAuto and liked you way better!

So far so good
