Paint Bronzing Problems

A not too common condition, seen more often in some dark blues, reds, maroons and rarely in other colours, having the appearance of a fine coloured chalk or bronze coloured film on the surface. Easily wiped off, the condition appears again in a short time. The painter has little or no control over this rather rare condition.

Cause
1. A peculiar combination of certain pigments and film-forming ingredients is responsible.
2. In a few cases, overheating of reds and maroons by hot spraying or wheel burning has been known to cause this condition.

Prevention

Repair
1. Light hand polishing with a mild liquid polish will remove the bronze. Frequent washing and light polishing will maintain good appearance.
2. Permanent elimination of the condition usually requires repainting.
