Auto paint spray defects - wet print or wax marks under the coating：
From the surface of the paint layer, you can see the outline of the contaminated area on the bottom layer, or the appearance of matt spots of various shapes.
(1) Cause:
①The underlying surface is not thoroughly cleaned before painting, for example, grease or wax is not completely removed.
② The previous paint layer is not dried or the defects of the old paint layer are not removed.
③ The previous paint layer is incompatible with the re-sprayed paint layer.
(2) Correction method:
If the wet print is more obvious, it should be sanded off the paint layer and re-sprayed.
