Should add to the compition the long term test. See how side 1/2 are in a month. Inspecting visual appearance as well as feel. Continue with normal everday things, i.e. carwashs, but no extra wax added. Of course that would be up to the partcipant that got there car waxed.
I am intrested to see how the zaino holds up. It definitly "felt" the best.
