Pennant Primer is a waterborne, two-part epoxy coating specifically formulated as a tough, below-the-waterline primer for marine topcoats. Though Pennant Primer was specifically designed for use with System Three Pennant Topside Paint, it is compatible with most commonly available marine topcoats.
What started as an epoxy company in 1979 has become so much more.
In addition to our laminating resins, adhesives, putties, and pastes, System Three also offers world-class finishes. Our Pennant Primer and Topside Paints plus our ever-popular Spar make System Three the choice for your next boat.
