Frequently Asked Questions

How do I choose the right type of automotive primer for my project?

Select primer based on substrate (metal, bare steel, aluminum, plastic, or existing paint), desired finish (high-build for filling, etching for bare metal), and compatibility with your topcoat—check whether the primer is epoxy, urethane, acrylic, or etch/cleaner-based and that it adheres to the materials you’re working on

Are there primers that work for both metal and plastic panels?

Some multi-surface primers are formulated for adhesion to both metal and plastics, but not all plastics are the same; look for primers that explicitly state compatibility with automotive plastics and, when in doubt, perform adhesion tests or use a plastic-specific adhesion promoter

What price range should I expect and does higher cost always mean better performance?

Automotive primers commonly span budget options under $50 up to professional-grade products over $150; higher cost can reflect specialized formulations, faster curing, or rust-inhibiting properties, but choose based on chemistry and suitability for your application rather than price alone
