Our 1965 Chevelle's paint looked really nice coming right out of the spray booth, but we knew that by wetsanding and buffing the car with 3M's Trizact system, this car would have a perfectly flat show-car finish. The process involves wetsanding the car by hand as well as using air-powered dual-action sanders to level the finish, then a variety of buffing pads and compounds to polish the car to a mirror finish.
