Description of problem:
The paint is pushed in the form of craters. These craters vary in thickness, density, and size (from a pinhole up to a diameter of 1 cm). A close inspection with a magnifier shows the presence of a small impurity in the center.
Causes:
Contamination by wax, silicone, oil or grease.
Contamination by soap residues, detergents or metal cleaning products.
Contamination of the surrounding air (proximity to mechanic shop).
Contamination of the air supply.
Contamination from use of polishes or aerosol spray containing silicone.
Preventive measures:
Make sure that the surface is thoroughly cleaned after every operation with Genclean 8281. Use a new rag for every car.
Make sure that all products containing silicone are used as far away from the workshop as possible.
Remedy:
Apply mist coat.
Sand panel, isolate and repaint.
Use antisilicone 8678 as a last resort.
