Re: Metallic copper dinghy paint?
tanks, nicer concept but apparently pure copper doesn't kill crud as well as the copper oxide used in bottom paints.
What you've invented is basically the same as the "copperpoxy" type bottom paints, which have received at best mixed reviews over the last decade or two. Many folks have tried them and gone back to bottom paint while a few still swear by them.
3M may still sell copper foil with an adhesive backing, it is used for electronics shielding and grounding. They had put copper sheeting on the market specifically for boat hulls/bottoms, maybe 20 year ago, and the product eventually disappeared.
So nice concept, but the "prior art" indicates bottom paint will be better, faster, quicker, cheaper, more effective. For a real test, you'd want to do the bottom half-and-half and see what actually happens.
