Paint correction is a detailing process that improves a vehicle's paint finish by removing imperfections like scratches, swirl marks, water spots, oxidation and hazing using a machine polisher and specialized compounds. This should only be done by professionals, due to the inherent risk of damaging your paint if polished incorrectly. By removing these defects, you restore the paint’s original clarity and luster. Paint Correction is usually done prior to adding protective treatment such as ceramic coating or paint protection film.
