    Back in the 70's ther was a product from BF Goodrich called No Foul.

    It was like 3/16 or 1/4 inch scuba divers wet suit material , epoxied to the hull.

    10 Year guarentee , only problem was the active material was Mercury, and the tree eaters didn't like that very much.

    I believe it still exists , for submarines , guess the Navy's of the world would rather stay alive than not.

    My black water tank has that capacity, but production is so small I cannot even sustain a small pilot light to burn off the smell:D:eek: - - - but had ti install an anti-flash-back-device, as tank explosion is not a pleasant event...

    No-Foul

    Actually that material No-Foul was developed for use on the submarine sonar domes, and as such metal based antifoulatants were discouraged. It was the organic TBTF (antifouling agent, tributyltin fluoride) agent that was impregnated into the elastic rubber material. It worked.

    Hey Fred, I just discovered we had this discussion before:

    Maybe some of those impregnated materials were metallic...sure would surprise me.

    Even that doesn't protect it from cookie-cutter sharks, which have a nasty habit of attacking the leading end of anything they might find delectable.

    What happened to arc sprayed copper or zinc? Supposedly can be applied to anything (doesn't heat the surface significantly) and is fine for the environment.

    Water Based Antifoul Paints

    Since the fall of '07, this writer and her husband's boat has been part of a bottom paint study to test the efficacy of the biocide Econea, an eco-friendly product produced by Janssen Pharmaceutica and sold to different paint companies. Three paints were applied to the bottom of our Crealock 37 — one control paint containing 67% copper, one solvent-based test paint and one water-based test paint. After a year, the water-based paint, in our opinion as boat owners, was not only the best among the three, but the best paint we'd ever used. There was zero hard growth on all three — which made them equally 'successful' in the eye of study coordinator Jack Hickey, as that is the study's primary focus — but the water-based paint had very little slime or grass. The other two were mini-ecosystems unto their own

    "They dissappeared and now someone is selling as if they were new. I wonder what happened to the old units and how well they worked.",
