I myself love Duragloss wash, 301 I think is the number. It has excellent lubricity, and it smells great! I've had good luck with Menzerna polishes. I agree with Venom though. I've tried a few different waxes, and at least once you polish the car, I really don't see a difference. I do feel the cheap stuff doesn't last long enough, but I wouldn't go spend a lot of money on wax. If you want a good sealant that lasts a long time, go get a bottle of Collinite 845 wax. A couple coats of that stuff, and you are good for 3-6 months depending on the conditions.
