I detailed this 1997 BMW M3 just before Christmas (polished with Meguiars DACP to remove some minor swirling, then used Megs Swirl Free Polish then Clearkote's Vanilla Moose before waxing with S100 Paste Wax) and the lady called me out again late last week to wax it again since it had been washed at the dealer and they left streaks in the paint. The weather had been dry, but the car was left under a tree at the dealer and had some light sap and dust on it. She needed me to finish within 90 minutes since she had to pick someone up at the airport, so I really didn't have time to wash it (yes, even with QEW) and wax it and guarantee she could leave in 90 minutes, so I went over the whole car with Quikshine.
I think the results speak for themselves. The first pic is before and the second immediately after using Quikshine and before waxing it again.
