repair minor damage – where?

Hello, unfortunately I have some minor paint damage on my Golf III and also some scratches on the bumper. Now I have seen some time ago a car show on television where an apparently larger workshop chain has specialized in such minor damage (also holes in the seats, etc.) without much effort to repair in rather unconventional way very cheaply. The results shown were impressive. Therefore I would like to know if anyone, the name d he probably is well known throughout Germany represented workshop chain and often even made experiences mfg rodmaen
