Fender Delle – 3 opinions

Good day, at my Golf 7 GTI Facelift there is an approx. 3-4 cm long vertical dent at the rear right side of the fender. With a small paint damage, however, exactly on the edge. The causer was found and we agreed to handle the whole without insurance. I contacted 3 different workshops and received 3 different opinions. 1.) Contract workshop of VW Cost point approx. 1000€ Method: Paint the whole part from bottom to top and top 2.) Painter and also bubbling doctor Cost point approx. 600€ Method: paint up to half height and then polish the transition. However, he warned me “that he must fog towards the interior!?” 3.) Mobile dent service Cost point approx. 300€ Method: remove tires, disassemble inner lining from the wheel box, dent. Then paint pin and polishing. I wonder if painting for the “small dent” is not too much effort. Car has been accident-free so far – year 2017. My concerns are also that one perceives the color difference rather than the small paint damage!? However, I have to say that the paintr does very good work and was recommended to me by 3 persons. Without painting, I estimate that the paint damage on the fender always remains visible because the reflection on the edge is interrupted and remains. Furthermore, it could also be wrongly polished here by being polished directly on the edge. r the damage and what method can you recommend me? The costs play a subordinate role for me.
