What is Primer (Primer Surfacer)?

Etch primer is used on bare metal. Primer surfacer fills minor scratches and is sanded smooth. Epoxy primer gives strong corrosion protection. Each layer must dry before the next coat is applied. The primer colour can also affect how the final colour looks, so painters choose grey shades to suit the top coat.

How it works

Primer bonds to the substrate and gives the colour coat an even, adhesive base.

Why it matters for your car

Bare primer left unpainted absorbs moisture. Use a primer compatible with the paint system.
