Hello, I still have an A4 B6 from 2004 in the color brilliant-black, color code LY9B. Soon the fenders are to come to kulanz because of rust and be painted. The tailgate also comes as a used part new, but should also be painted. I would say that the car has an age-appropriate varnish. However, compared to a half so old A3 Sportback, which also has just under the same km-performance, about 200Tkm, and has exactly the same color code, the A4 shines clearly less. Just as I picked it up, the paint will be adapted to the “weather conditions” when it is painted. But if I wanted to polish the car later on, I would be afraid that there is a possibility that the old sheet metal parts will then radiate / shine significantly more after polishing than the newly painted ones, because they were trimmed to “old”. Otherwise, one could also let paint “new” in the mixture in the hope that the old ones will be painted In addition, my idea now would be to polish the car, then paint it, and later again polish the newly painted parts to obtain the same finish. Who can now tell me whether my fears are right or what I should do best? Thanks already in advance.
