If you live close to or are willing to drive to San Jose, I'd recommend AJ Auto Detailing (702 Coleman Ave, SJ, a few blocks from SJ Intl. Airport). I took my twilight blue G35 sedan to them a few days ago to get some swirl marks removed. They took almost 3 hours to detail the car, remove the swirls, and put on a polymer sealer wax. They really do take their time. They also don't use recycled water to clean (like a lot of car washes do) and actually use their own non-tap water during the final wash to prevent water stains. They've been consistently ranked as the number one auto detailer in the south bay area. I was really impressed with the final results. They're open from 8am to 6am, Monday through Saturday, and dont' require appointments.

 

If you want to get the "5 year warrantied" service, you'll pay close to $300. I chose the non-warrantied service and paid $135, which seemed like a good price considering the results.

 

I had put the recommendation to the place in Burlingame. It was okay, but can't tell you any long term effects because my G is now at the body shop after someone gave it the hit and run in a parking lot!
