A wash removes dirt and contaminants from the surface. Paint correction removes defects from the clear coat itself — swirl marks, light scratches, oxidation, water-spot etching — using a polisher and progressively finer compounds. The result is paint that looks deeper and clearer than a wash alone can produce.
A wash is part of every detail package. Paint correction is the differentiator between Silver (no correction), Gold (single-stage correction), and Platinum (multi-stage correction). The more stages, the more defect removal, but also the more clear coat material is removed — there's a finite amount, so over-correcting a car shortens its lifespan.
Most cars don't need multi-stage correction. We'll tell you straight if a single-stage gets you 90% of the way there at lower cost.
