Star brite Professional Grade Mold & Mildew Stain Blocker - 32 oz

Why you'll want it

• Helps keep mold and mildew from returning. It is made for many surfaces, including fiberglass and vinyl, to help keep stains from coming back.
• Protection you cannot see. The barrier is invisible on treated surfaces, so your boat keeps its clean look.
• Less time spent scrubbing. Your surfaces can go longer between washes and still look fresh.
• A good job before winter storage. Apply it this fall, before winter storage, so the barrier is in place before the boat sits.
