What type of primer should I use for automotive applications?

Automotive primer selection depends on substrate material: epoxy primer for bare metal provides excellent corrosion protection, adhesion promoter for plastic components ensures proper bonding, high-build primer fills minor imperfections, and etch primer is essential for aluminum and galvanized surfaces.

How do I calculate primer coverage for different application methods?

Primer coverage varies by application method: spray application achieves 100% efficiency, aerosol spray about 70% efficiency, brush application 50% efficiency, and roller application 60% efficiency. Our calculator automatically adjusts quantities based on your selected application method.

What factors affect automotive primer adhesion?

Primer adhesion depends on surface preparation quality, substrate cleanliness, primer type compatibility, environmental conditions during application, and proper curing time. Clean, properly sanded surfaces with appropriate primer selection ensure optimal adhesion and long-term durability.

Q: How much primer do I need for my vehicle?

Primer requirements depend on vehicle size and surface condition. Compact cars need 1-2 quarts, mid-size cars need 2-3 quarts, and large vehicles need 3-4 quarts for complete priming. Bare metal surfaces require 25-50% more primer than previously painted surfaces due to increased absorption.
