Barrier Coats

Protect your hull from this year and beyond with our various lines of Barrier Paints, including Interlux, Mercury, and Pettit.


Pettit Paints offers maximum resistance to fresh or salt water and offers several options to protect your boat from water absorption, gelcoat or osmotic blistering, and corrosion. Save time and money with Pettit Protect’s high-solids formula that allows for a quicker and easier application. It reduces water absorption in fiberglass hulls, making it an excellent choice for the prevention and repair of osmotic blisters. It is ideally suited for commercial and pleasure craft applications and has excellent durability. AlumaProtect is specifically designed for Aluminum crafts, and is similar to Pettit Protect. Intended to be used as a primary coat over bare aluminum hulls and outdrives. Pettit Protect High Build Epoxy Primer is an excellent choice for the prevention and repair of osmotic blisters.

Skip the sanding with the Interlux InterProtect line. Interlux Interprotect is a unique two part coating, and is excellent for usage on underwater hulls, metals, and keels. Interlux developed it to protect new and used fiberglass hulls from water absorption, and corrosion above or below the waterline.

Mercury Corrosion Guard Paint was developed to protect painted and non-painted surfaces from rust formation on all metal surfaces, including outdrives, lower units, and power trim motors. Corrosion Guard Paint can also prevent further paint damage from undercutting and blistering. Not for usage on surfaces with antifouling or biocide paint.
