These craters, if not correctly removed, can recur as a result of a restoration painting as more flat recesses. Magnification (50 times) Magnification (100 times) Magnification (50 times) Crater seen from above Double crater Crater detail Cross section of a crater in the bottom CAUSES Mainly, deposit of oil, grease, wax and silicone residues (contained in the polishing products) on the support or on the applied layers. On the part of man - stains on overalls, use of rubber gloves and cosmetic products for the skin and hair. In painting booths - lubricants of moving parts, release agents from plastic components, pipes and sealing material, poor maintenance of the oil separator, of the water / oil filters and of the filters applied to the plenum and to the floor. In paint products - incorrect use of additives (anti-silicone), unsuitable diluent / catalyst, presence of impurities due to transport and bad storage. In the substrates being processed - residues of release agents on plastic parts, residues of lubricants, residues of welding material, bitumen and oils from insulating materials. Auxiliary operations to painting - release agents from new sponges, unsuitable cloths, detergents or abrasives, glue from adhesive tapes. Work environment - suction of contaminated air (polishes, spray oil, fine dust, etc.) from other departments / workstations of the bodywork, dust of insulating / sealing material from the building. PREVENTION The above points represent most of the causes of dodging. Referring to them it is possible to avoid the formation of the defect. In principle, it is recommended to use silicone-free products near the paint shop and to carefully wash the substrate. RESTORATION Sand the paint until it reaches the intact layers. Repaint using the appropriate paint system.
