I wash and dry, and then use Meguierr's RV/Marine 50. A two step product, but fairly easy to apply and remove, and it seems to last quite a while.
I tried Pinnacle XMT 360 Spray Wax, and that was a disaster. Left an oily looking rainbow "in" the wax. Had to use a cleaner/polish to get the Pinnacle off.
