The terms "stage 1," "stage 2," and "multi-stage" refer to the level of correction and refinement applied during this process. In a stage 1 paint correction, the focus is primarily on eliminating minor defects like swirl marks and light scratches. Stage 2 involves a more comprehensive approach, addressing moderate imperfections, oxidation, and enhancing gloss. Multi-stage paint correction takes it a step further, encompassing a thorough series of steps that may include compounding, polishing, and refining to achieve a near-perfect, show-quality finish. The choice between stages depends on the condition of the paint and the desired outcome, with multi-stage correction being the most intensive and suitable for achieving a flawless, high-end result.
