No, but they look well set up! If their techs are as good as they say, go for it!
I use touch up guys in Sydney, but then only a specific bloke. They are a franchise, so each worker is independent. He came well referred, and I have recommended him to others who are equally happy. He does not do wheels or metal panels though. He does do bumpers. Regrettably I have needed his services 3 times. He is nowhere near as well set up as the mob you mention.
