I detailed that Porsche today. Still in terrific shape. Excellent beading, good slickness with the 5 week mark. Car needed no polishing, so I just applied two more layers of AJ. Side by side vs a 5 week old application there was not much visual difference (slightly wetter looking) so it seems the initial look does hold on pretty well. I know the car has been through weekly tunnel washes-he is just too far away for me to do weekly hand washes-so it isn't like this is based on QEW washes only.
What I did notice is a bit more depth with each layer. Not huge improvements though. I'd say anything past 3 layers isn't going to pay off in time and product usage.
