Description
A series of deep cracks resembling mud cracks in a dry pond. Often in the form of three-legged stars and in no definite pattern, they are usually in the color coat and sometimes the undercoat as well.
Origin and Potential Causes:
-
Excessive film thickness. Excessively thick topcoats magnify normal stresses and strains which can result in cracking even under normal conditions.
-
Materials not uniformly mixed.
-
Insufficient flash times between coats.
-
Incorrect use of additives.
-
Substrate is too hot or cold.
-
Use of coats incompatible with each other.
-
Omitting the activator when mixing a 2K product.
Remedy
The affected areas must be sanded to a smooth finish, or in extreme cases removed down to the bare metal, and a full refinish system reapplied.
