you won't have those problems. That's if you wax twice a year and your car is in the garage overnite. If you don't garage your car, then do it every two months. Those that park their car on the street and wax only once a year or less are only kidding themselves. As a matter of fact, my first '90 Z32 (owned 7 years) was platium and my current '90TT (Cherry Red Pearl) never faded and looked great.
