I would recommend Dodo Juice Blue Velvet Pro:
1. Easy on / Easy off. No worry of towel marks when buffing.
2. Already contains a sealant, so you get the best of both worlds in 1 product.
3. Top notch beading / long lasting.
4. Color charging adds an "inky" look to dark paint.
5. You can try out a panel pot first for $15 to see if you like it.
6. Spreads like butter. I can see getting 50+ applications out of a full size tub.
7. Dodo makes 2 paint cleaners for this wax. One with abrasive, one without. You can taylor your pre-wax products to your needs.
8. Dodo's maintenance products are awesome.
9. This wax is very easy and fun to use. It smells like candy.
