Hi Todd - I agree with DK and others on the benefits of Z6 -- amongst other things, it replinishes the paint protection system.
BUT, I think experimentation is important. So, I would say, "go ahead" -- try waxing over the Zaino (the world will not end) and share your results with us.
I would suggest waxing one half of the car (the right or left half, splitting the car down the middle), then observing the results and comparing the two halves over several days. If you like the result, you can wax the other half. If you don't like the result, you can Dawn wash the car, then Z7 it to remove any detergent film from the Dawn.
I'm really interested in the results of the experiment.
