I recently purchased a slightly used Chysler Crossfire Coupe - Silver Blue Metallic. I did the whole Zaino drill(Dawn,Clay, Z-2 X4 layers,Z6 between layers). On a whim I topped the Zaino with Duragloss AW and am very pleased with the results. It seemed to enhance the shine and slickness better than the Z6. I am wondering what will happen if I add more Zaino Z2. I will try it soon and see what happens. Has anyone out there in forum land experimented with other Zaino toppings?
