Funny this was/is the exact same plan that I have had for this winter. believe it or not.!! have been testing carnuabas on the hood of my truck for the last three weeks. Having had Zaino previously on the truck the souveran looked compareable for about two weeks. the last ten days I have been feeling a grit build up on the surface of the Souveran. The wax is not what it used to be. To say that I am disappointed would be an understatement.
I look forward to your results in the coming winter. I truly hope that you get what you are looking for in a shine. Even though my test should continue for complete results, I have to admit that my resolve is waining. I want the Zaino shine that comes in the disguise of protection and durability.
