C4 stands for Clear Cut Correction Compound. This best-selling compound is more abrasive to remove deep imperfections on paintwork surfaces. It quickly removes defects, scratching, acid rain marks, etching, swirling, holograms, and 1200+ grit sanding marks.
Unlike heavy-duty abrasive compounds that can leave marks while they cut, C4 leaves minimal compounding swirls & micro-marring, eliminating the need for additional paint refinement before final polish. And unlike other heavy-cutting compounds that produce copious amounts of dust and debris, adding work time to your job, C4 polishing compound produces low dust, so you can get on with your day. For the ultimate shine, follow this up with P4 Polish.
