Pettit Prop Coat Barnacle Barrier 1792 is specifically designed to be used on bare metals such as steel, stainless steel, cast iron, copper, bronze, galvanized steel and lead, both above or below the waterline. Prop Coat forms an excellent adhesive bond to underwater metals and running gear and inhibits corrosion on these surfaces. Properly applied, Pettit Prop Coat Barnacle Barrier yields a smooth, hard surface that self-cleans under way.
Do not apply anti-fouling paint over Prop Coat. For metal above the waterline apply one (1) coat of Pettit 6627 Tie-Coat Primer after the Prop Coat has dried for 2 hours. Follow with two (2) coats of Pettit Easypoxy Enamel. The dried film of Prop Coat contains 93 percent pure zinc.
Choose from 20 oz. Aerosol spray or Quart can.

I have used this in the past to paint my Max Prop propeller. This time the spray can worked for one thin coat and after stopping for one minute it would not spray again.

Product prep was easy. Application was simple, and the look was great. We keep our boat in the water, so will see how long it works for us.

Appears to work as good as, easy to use and much less expensive as the current alternatives

Just clean the surface with a rotary brush and acetone. Let the acetone dry. Spray on two coats covering all exposed metal surfaces.

Used this paint for the first time last season because my prop was perpetually fouled at haul out. Had previously used ablative bottom paint. Application was easy and fast (<5 minutes) once I got down to bare metal. Be sure to not apply too much. As a test I never cleaned the prop during a long sailing season. It came out with essentially no growth and none of the paint was worn off. What growth was there I could flick off with my fingernail, leaving the paint intact. Preparing for this season will probably require a little more elbow grease than before, but it's worth it. For me, one can will last several seasons.
