SINKAGE PAINTING DEFECT: CAUSES AND SOLUTION – SINNEK

Sinkage, also known as paint loss or sinkage, is a usual repairing defect at the bodyshop. This application error occurs when the final coat of paint has dried and has a kind of surface sinkage in the repaired area. Sinkage is often related to an incorrect preparation of the intermediate coat, especially during the putty application phase, hence they are also called putty sinkage or patch marks.
