CHALKING

A chalky white appearance on the surface of the paint film

CAUSE

1. Pigment is no longer held and protected by resin, resulting in a powder-like surface and lack of gloss due to:
   1. Natural weathering of the paint film;
   2. Improper application of paint material;
   3. Using generic thinner/reducer and/or hardener in the paint material;
   4. Excessive use of mist/fog coats when applying single stage metallic finishes.

REPAIR

1. Compound to remove oxidation and polish to restore gloss.
2. Or, sand to remove "weathered" paint film and refinish.

PREVENTION

1. Weekly washing and occasional polishing or waxing will remove oxidation from the finish.
2. Thoroughly stir, shake or agitate all paint materials.
3. Use the recommended thinner/reducer,hardener, and measure accurately.
4. When spraying single stage metallic finishes, apply mist/fog coats panel by panel while finish is still wet.
