My Vette was detailed on 3-18-06 by forum member gmblack3a.
It has been almost four months since the detail. I have washed the car once or twice using Zaino car wash, QEW a few times, and with PB SnW a few times. I have put on PB Spray-n-Gloss a couple of times. I tested some Collinite (sp) 845 on the roof and hatchback panels. The car is a weekend driver and is garaged. The car got caught out in the rain today when the missus was out and about. It beads very nicely and still feels smooth.
Here is the detail:
