Why Paint Jobs Fail

YELLOWING:

A paint or varnish is said to yellow if it develops a yellow or brownish discoloration. Yellowing may be caused by lack of natural light (sunlight), or in some instances, by exposure to sunlight. Other contributing factors are moisture, heat, fumes, or misuse of a product.

Certain paint additives on the market contain ingredients that cause yellowing. Additives should never be used unless recommended by the manufacturers of the paint or enamel.

Technical improvements incorporated in modern paint products have materially reduced or eliminated this yellowing tendency. Where a coating is subjected to fumes or other unusual conditions, only products recommended for that particular environment should be used.
