Appearance testing
The paints and varnishes applied to vehicles may be damaged by exposure to the effects of the brushes in car washes.

This test reproduces, in the laboratory, the action of a rotating brush fitted with synthetic bristles. The severity of the test can be increased by adding an abrasive solution while rubbing the brushes on the part.

The results are expressed in terms of the loss of brightness of the sample.
