Pettit Marine Prop Coat Barnacle Barrier
$34.99 (16-ounce can); www.pettitpaint.com
Pettit’s new Prop Coat Barnacle Barrier is an aerosol spray coating that shields bare metal—including steel, cast iron, stainless steel, aluminum, copper, bronze, lead, and more—above and below the waterline. Barnacle Barrier dries quickly, and with two to three coats, will protect bare metal from corrosion and preserve surface integrity. Prop Coat Barnacle Barrier produces a flat-gray finish and one 16-ounce can covers 10 square feet of metal.
