Collinite No. 920 Fiberglass Marine Cleaner is a pre-wax compound formulated to cut through mild-to-moderate UV oxidation, chalkiness, discoloration, black streaks, and tough stains that regular washing leaves behind. It restores original color and gloss to fiberglass surfaces, leaving a clean, smooth foundation that improves wax bond, spread, and long-term durability when followed up with a Collinite finishing wax.

Features:

• Removes mild-to-moderate oxidation and chalkiness
• Eliminates black streaks
• Lifts tough stains that washing alone cannot remove
• Leaves a clean, smooth surface optimized for follow-up wax application

Specifications:

• Size: 16 oz
• Compatible application methods: by hand, dual-action polisher, or rotary buffer
• Average spread/coverage: 250–500 sq. ft.

Application by Hand:

• Apply a nickel-sized amount to an applicator pad
• Work the product into a section no larger than 2×2 ft using firm pressure; rub until just before the product begins to dry, then buff off with a microfiber towel

Application by Machine:

• Place five small pea-sized dots onto the buffing pad — do not over-saturate
• Set pad on the panel and start the buffer at 5,800 OPM; make 2–3 passes with firm pressure over a 2×2 ft section

• Wipe off residue to reveal a clean, glossy finish
