Automotive spray paint can be tricky to work with. The wrong temperature, the wrong application or the wrong color match can ruin the job. While an easy coating can be achieved with a one-coat application, a truly glossy, professional-looking finish frequently is obtained using the two-coat approach. As a result, true aficionados of car restoration tend to steer toward the two-stage paint approach for automotive painting.
Single-stage or one-stage automotive paint is just that — a one-application paint method. Assuming the automotive surface already has been prepped and primered to accept new paint, the one-stage paint is applied evenly in multiple coats and then left alone to cure and harden. Two-stage paint also involves a prepared surface, but then a base coat is applied and followed by a clear gloss coat.
