I had tried Zymol Glasur, Concourse and Swissvax Best of Show
Glasur: Good durability, Easy to apply and to buff off, Glossy looks esp good on silver
Concourse: No more durable than Glasur, Pain in the a** to apply and buff off. Harder to melt on hand. Much deeper rich looks when compare with Glasur. Great for darker paint
Best of Show: Less durable than both Zymol wax . Smell gorgeous. Easiest to apply and to buff off. Finish similar to Concourse
I prefer Swissvax on my carbongrey GTI
