Meguiar’s M6732 One-Step Compound removes heavy oxidation from solid gel coats! This one-step compound is specially designed to both clean the gel coat’s surface and leave behind a high gloss finish. It will remove moderate to heavy oxidation, stains, scratches, and tough hard water spots by hand or machine, restoring the color and leaving a rich gloss on the treated surface. Aggressive, yet safe. Reduces the steps to treating neglected surfaces by combing a compound and polish into one easy step!
