Wax, Glaze, or Ceramic coating ?

My friend Treius who is a Gray police officer and runs his own landscaping and tree service and car detailing swears by the ceramic stuff, but he gets high end products not available in any of the parts stores. He has a lot of high end clientele up around Lake Sinclair. Big money. So he uses the best products he can find. I don't know what he uses, but I can find out if you like.
