501-36-66 Paint - General Information 501-36-66 DESCRIPTION AND OPERATION TO BE UPDATED LATER NOTE: Choose a suitable profile diameter. A profile which is too thick will protrude from the opening, one which is too thin will leave a gap. Clean the door opening well and affix the matching shape. Color shade problems If a vehicle color shade is taken from a vehicle on a hot summer day and the mixed color applied, this may cause color shade problems. Some colors change so much at higher temperatures that it can lead to an incorrect result. Red color shades are particularly prone to this shade behavior. This means that color determination should always be done on the bodywork when it is at about the same temperature as the later working temperature will be. The best temperature of the item is between 15° and 25° C. Isopropanol and water Painted surfaces are very easily cleaned using a mixture of 70% water and 30% isopropanol (can be obtained through a laboratory supplies specialist or a pharmacist). Temperature reduction spray If finishing work must be performed on touched-up surfaces and newly painted plastic parts, problems may arise. The paint and the transitions are not yet fully hardened. NOTE: When working with the polishing machine, make certain that each operating run lasts no longer than about 5 - 10 seconds, in order to prevent the paint becoming warm. Even so, in order to be able to polish over transitions, temperature reduction spray must be applied to the surface. The transition area is then alternately sprayed and polished until a perfect transition surface is achieved. Paint faults on soft plastic components where elasticizer additive has been used in painting must be wet sanded using grade P2000 - P2500 paper. In doing this the sanding location and the surroundings are sprayed with temperature reduction spray and the paint faults sanded out by hand. Afterwards the location is polished as described above. Paint plane Dirt inclusions and paint runs can be removed with the sanding cylinder ("Finiball") and hand sanding or eccentric sander in a wet sanding process. Another practical tool for removal of paint faults which lie proud of the surface is the paint plane. NOTE: Guide the tool carefully with the minimum of force. It must not tilt, otherwise more serious damage may easily be caused. TO BE UPDATED LATER This tool allows paint faults to be carefully removed in shavings. Afterwards the surface must be polished using suitable materials. Shading Even when all the rules, steps and corresponding instructions have been followed concerning possible shades, it may happen that the mixed color shade does not exactly match the vehicle color. In these cases, shading must be done. Because there is no fixed formula for this, experience and a trained eye are important. Some rules must be followed for shading. NOTE: Self-made color sample plates of the current colors are very helpful for determining the
