I used this guy when I lived in Keller. he did a nice job on a black carrera. mobile service. Scott's Mobile Auto Detailing :: Home
Not sure where exactly you are compared to some of the guys but look for Kody Keuter with New Image Auto Detailing. Great guy that knows what he is doing, he is also a Cquartz Finest installer. New Image Auto Detailing
Tomato Werks is highly regarded among the Porsche community. Full disclosure - I've never personally used them...T
You might try calling Wash Doc mobile detailing. The owner's name is Donnie Anderson and I have used them on several personal cars and for cars at our classic car dealership.
if you are doing any considerable repaint, check out Stuarts paint and body. They do boardwalk painting and I just had them redo my frontend, which had a lot of rock dings on it.. Car looked like new, they did a great job.. Then I followed up with a clear-bra install from Invisibra, also did a great job..
+1 on Stuart's. They did the PDR on my Porsche after its run in with a Texas hail storm. Car looked better than new when they were done with it...T
