One Step Heavy Duty Cleaner Wax with PTEF is formulated specifically to remove oxidation and hazing from fiberglass or painted surfaces. The PTEF polymers seal the restored finish to keep it looking its best, while providing unmatched protection against UV rays and a deep, long-lasting gloss. Application is simple, whether by hand or with a buffer; apply, let dry to a haze and wipe off. For best results, protect the restored finish with a coat of Premium Marine Polish with PTEF.
