The pros ALL use 3M products. You can buy them at many autoparts stores - just ask for them, as they are in the back.
2nd best are the products from Meguires. Unless you wax regularly (every month or less), you need to evaluate your paint first. No sense in sealing the garbage in. If you are anal and wax every month (Brian), then you can choose a wax product and stick with it.
All in one products tend to do all poorly. BTW, Zaino makes great wax products. But, with any wax product, the surface better be good first.
