I had a nightmare "detailing" job performed by my local Nissan dealership; I'm assuming that they were busy that day and had the guy who normally sweeps the floors do it. The paint job wasn't exactly perfect going in, as I'd let the local car wash clean it (never again... it's all me from now on), but it looked much worse, like the person who did it had never used a buffer and didn't know that, if you drop the buffer into a pile of gravel, you need to do something besides picking it up and going back to work
Anyways, I posted here looking for a detailer in SoCal and was told that there is a guy in Anaheim named Richard Lin who specializes in black cars. I'm going to link to his detailed posts with lots of nice pictures and commentary, but the bottom line is that he worked miracles with the car. He spent (this is not a typo!)
23 HOURS on it; I think he is the definition of a perfectionist. If you ever need proper detailing, please look him up.
Here's the thread:
