Use It With

Marine and Boat Polish and Sealant removes superficial defects and scratches to produce a brilliant shine, then leaves behind a coat of sealant to protect and maintain marine surfaces from future contaminants.

Use This To: 

  • Remove defects and scratches
  • Polish gel coat, fiberglass, and more
  • Protect against marine elements
  • Polish and protects in one-step
  • Restores a boat or watercraft to a deep shine

Fast Defect And Scratch Removal

Boats and watercraft are constantly exposed to harsh elements. Improper cleaning and surface abrasion scratches and damages surface gelcoat and fiberglass, which leaves swirls and deep scratches in the finish. Extreme temperatures, UV light, and corrosive salt spray oxidize finishes and turn them chalky and white. Use Boat Polish & Sealant to polish the surface and remove swirls, scratches, oxidation, and defects for a mirror shine on any boat finish. Machine polishing is the only true “fix” for scratches, swirls, oxidation, and defects.

Enhanced Protection Against Water Spots

The sealant contained within this polish bonds directly to and fill the microscopic pores on the surface of paint, gel coat, fiberglass, plastic, polished metal, glass, and more. With the pores filled in and sealed against the environment, the treated surfaces reject future staining and contamination from water, salt spray, oil and diesel, UV sunlight, pollution, industrial fallout, marine life, and mineral buildup. Boat Polish & Sealant restores gloss and shine, and protects the new finish from contamination and staining for up to 6 months.
