Liquid sandpaper aggressively sands badly scratched, dirty or chalky gel coats without creating sanding dust. This liquid sanding suspension also establishes clear conditions at repair sites, resulting in ideal surface preparation for subsequent polishing. Get the best results in the least time – gel coats tend to be much thicker, harder, and more porous than clear coat, and as a result this product is formulated with more aggressive abrasives and special chemistry to prevent the liquid from being absorbed before it can be worked over the surface. Automotive compounds will work, but can result in greater product usage, more time spent, and less desirable results.
