Two-coat enamel

As the name implies, two-coat enamel is applied in two operations. The first coat, the base color, contains the pigment, metal flakes and binder. The second coat consists of a clear enamel, which provides the final gloss for the paintwork and protects the base from moisture and environmental con- taminants.

Touch-up stone-chip damage as follows:

1Thoroughly clean the damaged area.

2Apply the primer, base color and finally, the enamel. To achieve the best finish, apply two or three coats of primer.
