For a couple years I used Topoftheline's Trade Secret. Last year I bought a can of Jorgen's GT 20/20 Paste Wax from eBay. I'm now on second can from his website. I have done 3 black vehicles and a Mazda Turbo6 in a dark metallic purple and all cars have come out looking great. The wax upholds pretty well in the midwest weather. The wax is a white carnauba and applies really well. Micro-fibers do a great job removing the excess. For $60 a pop it could be in my limited experience opinion a lot of bang for the buck. I imagine one day curiousity will lead me to another wax. its just the nature of man to hunt. Anyone else work with this wax? Mark
