First off, the color of the wax doesn't make a significant difference if you are sticking to 1-3 layers. Some people are adamant in putting a dark-colored wax on dark-colors cars, light wax on light-colored... etc.... Dodo's forum has posts indicating this is not necessary. However, the scents from the various waxes range from very good to awesome; making it a pleasure to wax by hand (fingers actually). If you are going to use a polisher then you may want to consider larger pots or a wax stick (which I don't think AG sells).
If you want a Dodo 'nuba look then (2) 30 ml. pots would be where you should think to start off.
General Approach
Layer 0 - Prep as you deem necessary
Layer 1 - Dodo Juice hard wax
Layer 2 - Dodo Juice soft wax (soft always on top of hard)
Layer 1 can be replaced with Supernatural or Supernatural Hybrid. Both have a higher concentration of 'nuba. This variation will be a little more expensive than the hard/soft combination.
If you only want to try 1 pot then go with the soft wax and be sure you have a good sealant on the car.
My typical approach is 1 layer of hard and then 1 layer of soft. When I want to go a little over-the-top I apply 2 layers of hard and 1 soft. I do this all by hand (fingers) and I get a great workout. My grip strength has increased significantly in the last year.
