First time using Zaino products. I am pretty impressed with the results and would definitely recommend. Just wish they weren't so pricey. This is the process I used. I just bought this car and it had heavy swirl marks.
Step 1: Wash with Dawn to strip all old wax
Step 2. Zaino Z-18 Clay-bar (keep wet with a mix of Zaino Z-7 Show Wash and water in a spray bottle)
