Thanks for all the replies guys... I did the wifes car with 3 coats of Z5.... and got some Autoglym EGP to top it off. It came out looking great and I am very happy with it. But for the M3, I am thinking of doing like 5 coats of Z5, and leaving it at that.... the Z5 by itself left a really wet looking finish I think
Didn't see Duragloss represented, so here goes. Some pictures of Duragloss 105 topped with Duragloss AW. The car is a 6 years old, daily driver parked outside 24/7 and has 83,000 miles on the odometer.
On my dark silver Corvette, UPP achieved the wettest look out of all the other sealants I tried. I recently topped it with #16 for a long road trip and it was still very liquid shimmery.
