If you care for a shiny vehicle, a paint polish or correction may be something for you. A paint polish decreases any paint imperfections to give you that glossy appearance. Swirls, scratches, and marring are unavoidable but fixable. There are three different levels or stages in paint correction. A 1-stage polish reduces and cleanses light swirls marks. A 2-stage polish is best for cars that haven't been polished in a couple of years or are in good to fair condition. If left unattended, these marks can become excessive; a 3-stage polish may become necessary.
