Collinite No. 920 Fiberglass Marine Cleaner (64oz) is an effective pre-wax cleaning compound formulated to remove mild- to moderate-level UV oxidation/chalkiness, black streaks, discoloration, and tough stains that a wash will not remove. No.920 cuts fast yet finishes to a smooth surface, restoring original color and gloss to facilitate superior bond, spread/coverage, and durability of subsequent Collinite waxes. Suitable for hand, dual action and rotary machine application. For hand use, apply a nickel-sized amount on an applicator pad and rub a 2x2 ft section with firm pressure until just before product dries; buff with a microfiber towel. For machine use, apply small pea-size dots to the pad, operate at ~5800 opm for 2-3 passes, reduce to 4800 opm for 2-3 additional passes and buff until just before the compound dries. Average spread/coverage for smaller sizes ~250-500 sq. ft. (16oz baselines). Sold individually under Waxes & Polishes; ideal for boat maintenance to restore fiberglass shine prior to waxing and long-term protection.
