Marine 31 Stainless Steel Polish & Sealant Combo cleans, polishes and lays a long-lasting protective acrylic barrier on stainless steel, aluminum and chrome surfaces to restore mirror-like shine with minimal effort.

If you want to revive dull railings, hardware and appliance faces without aggressive rubbing or repeated treatments, this kit pairs a medium-cut liquid polish with a durable acrylic sealant formulated for marine environments and household stainless. The polish lifts oxidation and stains while the liquid sealant bonds to the surface, creating water-, salt- and UV-resistant protection that extends the time between maintenance sessions.

How does this combo remove oxidation and stains without harsh abrasion?

The Marine 31 liquid polish uses advanced abrasive technology that balances cutting power and a fine finish. It breaks up light corrosion and surface staining, then refines the metal to a smooth, reflective finish without over-sanding or leaving swirl marks.

  • Medium-cut action removes oxidation and minor pitting.
  • Ultra-fine polishing agents refine the surface to a bright sheen.
  • Formulated to avoid dulling or excessive material removal.

What kind of protection does the stainless steel sealant provide, and how long does it last?

The included liquid sealant cures to an acrylic-based film that repels salt, water spots and environmental contaminants. Under normal marine or household conditions it can keep treated surfaces protected for up to six months, reducing the frequency of polishing and cleaning.

  • Creates a hydrophobic barrier that reduces water spotting.
  • Helps resist salt corrosion, bird droppings and UV fading.
  • Typical longevity: up to six months depending on exposure.

Which metals and locations are safe to treat with this kit?

This combo is safe for uncoated stainless steel, chrome and uncoated aluminum commonly found on boats, appliances and outdoor fixtures. Avoid use on anodized, painted, powder-coated or pre-sealed surfaces to prevent removing intentional finishes.

  • Ideal: boat rails, cleats, hardware, ladders and appliances.
  • Not recommended: anodized or painted metal, porous surfaces.
  • Works well in both marine and household settings.

How do you apply the polish and sealant for best results?

Begin with a clean, dry surface; apply the polish sparingly and work it in with a soft cloth or polishing pad until oxidation is removed, then buff to a shine. Follow with a thin, even coat of the liquid sealant and allow it to cure per instructions for maximum durability.

  • Clean surface from grease and heavy grime before polishing.
  • Polish: small circular motions, then wipe off residue and buff.
  • Sealant: apply thin coat, allow proper cure time for full protection.

Who is this for: Boat owners, marine professionals, and homeowners who want a practical, time-saving way to restore and protect metal surfaces. If you maintain stainless railings, chrome hardware or uncoated aluminum fittings and prefer a product that combines effective stain and oxidation removal with a proven protective finish, the Marine 31 Stainless Steel Polish & Sealant Combo delivers a professional-looking result with less effort and longer intervals between maintenance.
