Aquatech Marine Rust & Stain Remover Gel dissolves rust streaks, hard water stains, and other stubborn marks from gelcoat, marine paint, and metal — without the damage that comes from aggressive acid cleaners. The thick gel formula clings to vertical surfaces instead of running off, giving it time to break down stains from the inside out. Lab-tested on polyurethane yacht finishes to preserve gloss and hardness.
