Just finished completing this today. My mate picked this car up about 3 days ago and he bought it to me to detail and seal it for him.
My plan of attack was:
Foam gun, rinse
Dish soap (to remove any wax the dealer may have applied)
Clay bar, dry
Polish with Menzerna SF4500 with orange Hydro pad on speed 4
WGDGPS (also did the glass roof and the rims with this)
Tomorrow I'm going to put a coat of Pinnacle Signature Series 2 wax on, and finish it off after that with some DG Aquawax.
Not much point with before pictures - the paint was in good condition, the car was just dirty with bird poo etc on it.
It's a really beautiful paint. The pictures don't quite show it, but it's got a green metallic through it, kinda like Lexus white.
