It looks like I need to give 476 a shot at some point. I'm at 14 weeks on the 845 and it still beads like crazy. Winter weather has set in here in the NW, and I've been traveling a lot, so I've only washed the car 4-5 times since giving it two coats of 845, which probably helps its durability. I also give the car a spritz of spray wax as a drying agent, which undoubtedly helps, too.
