Abstract
A substrate of either metal or plastic which is coated with a crater resistant enamel coating composition is used for the exterior of trucks and automobiles; the binder of the coating composition is a blend of PA1 (A) an acrylic polymer having hydroxy groups and contains about 0.1-10% by weight of a polymerized perfluoro carbon constituent of the formula ##STR1## where R is H or CH.sub.3, R.sup.1 is alkyl, R.sup.2 is perfluoro alkyl and n is 0 or 1 and PA1 (B) an aminoplast crosslinking agent such as an alkylated melamine formaldehyde resin; The composition is applied and baked by conventional techniques, to form a finish on the substrate that has an excellent appearance.
