Recommendation Lackdoctor/SmartRepair Stuttgart

Servus put together, the SuFu didn’t bring the desired success, therefore the new Fred. I did some kind of W****** scratch on the passenger door. Picture in the appendix. Now I’ve already scraped off a few painters. They all say “Repaint door for approx. 400,- plus fairytale control”. One of them suggested the paint pen (is still working?). Except for CarTop Stuttgart no smart repair offered. They do this for approx. 200,- without seeing a difference at the end with a guarantee of 2 years. Wanted to look again at ETF Carpoint in Sindelfingen and at Paint Fix Pro in Stuttgart today. Can you give the Scratch-Repar methods of the paint doc ́s believe that you really can’t see that? Was someone once at o.g. Lack pros? Have no desire to let me disasse half the car by the painter. Car: A6 4F FL in phantom black pearl effect Thanks in advance… mfg
