You won't get better than the werkstat stuff on white dude, honest truth right there. I could recommend anything but I doubt you'll get a better finish.
Do you clay, tardis your car? Also you could top with a nice wax like Supernatural for beading and sheeting ability, I know Jett offers good protection but waxes offer nice tight beading.
Wax should always go after Jett not before. Sealent then wax for future reference.
