This ultra-abrasive compound is engineered for severely damaged gelcoats and paints. COMPOUND PRO-MAX removes deep scratches and pre-polishes extremely dull or heavily oxidized surfaces, making it the first step in a complete restoration process. Apply to the surface with a brush or with the polisher turned off, working one zone at a time. Then use a polisher with high-density foam buffing pads until the desired result is achieved. Manual application with a microfiber cloth is possible, but for best results, use a polisher. For a flawless high-gloss finish and long-lasting protection, follow with P13 PRO-CUT, P12 PRO-MEDIUM, and P11 PRO-ULTRA FINE. Don't miss out on our specially curated Polish Bundle!
