Paintwork (repair)

Small paintwork damage, e.g., scratches and blemishes, should be repaired at reasonable prices and as quickly as possible. Accurate information as to when the car will again be available, is also important. Of course the quality of the repair should not suffer, simply to get the car out of the workshop quickly. The colour and surface must also perfectly match.

10 rules for the repairing of stone-chip damage to double-layer paintwork
1Clean the dry repair area with silicone remover (Q-Tip).
2Using a sharp-pointed (crafting-) knife carefully scratch out paint leftovers and old car-polish to provide a better paint-adhesion.
3Using a suitable instrument (e.g., a pipette or a fine artists brush) drip the (perfectly corresponding!) paint onto the damaged area. Normally, one drop is sufficient.
4It should be touch-dry in less than one hour.
5The protruding part of the droplet is then gently sanded down using (wet) emery paper or cloth (2000 grain) and a small sanding-block. A certain moisture is to be maintained. Check the surface for any remaining unevenness.
6Clean the repair area with water and let it dry. Repeat the previous procedure using clear varnish.
7This time the drying-time is substantially longer (1, or even better, 2 days).
8Sand down the protrusion in the same way as in 5. A slight overhang (almost invisible) is desirable.
9Polish thoroughly, also the surrounding surface.
10A one hundred percent invisible repair is sometimes a matter of luck …

The above figure shows a facility with which almost any colour can be mixed. It is economically important that only the amount required for the current repair is produced, thus avoiding unnecessary production and disposal costs. Minor parking dents often require only a tot-glass full of paint.
First of all, the colour code of the vehicle is important. If it exists somewhere on the bodywork as a sticker, one should always transfer it, e.g., into the owners manual. Having to search for the colour, using vehicle model and year of manufacture, can later be difficult and time consuming. Using the code, the exact composition of the paint colour can be determined, either by foil reader or nowadays, by computer.
Often there is also the possibility of colour choices which must then be compared with the actual paint colour on the vehicle. At this point the colour mixing is carried out using a very accurate set of scales. The multitude of colours seen in the above picture are not necessarily for the mixing of many different colour shades, but because of the varying paint compositions, e.g., the different solid components in the paint. If the car-drivers / manufacturers were content with using different colours only, one could get by with a fraction of the shelves.
Now the area to be repaired can be repainted using a very fine spray-gun, however, not before the area has been properly prepared and very carefully cleaned, to remove e.g., any substances containing silicone, Large scale masking may still be necessary. 07/11
