I bought the 4 pack to try these out on each of the cars (2 silver cars, one orange and one black). I used the bananna on the orange and it worked pretty well, although i wasn't as satisfied w/the white on the silver car. Granted it is a 22 year old car. We will see how it goes on the black car next month. It's a little tough getting wax from the smaller containers, but on sale, i think it was a good idea to try these out.
