Heavy cut polishes are important when dealing with severe paint imperfections. These polishes are formulated with aggressive abrasives designed to remove deep scratches, swirl marks, oxidation, and other significant defects from the paint surface. Their importance lies in their ability to restore the paint's clarity and shine, preparing it for further refinement and protection.
Heavy cut polishes can effectively level uneven surfaces, improve paint adhesion for coatings or waxes, and enhance the overall appearance of the vehicle. However, caution must be exercised when using them to avoid excessive paint removal and to follow up with lighter polishes for a refined finish.
