Chuck's idea works well, and has been doing so for years.
California has been cracking down on the amount of copper in paints for a long time, so while I was living there I first used paint I purchased from government surplus.* That stuff had a really high copper concentrate.
When I could no longer find*government paint*I shot oleoresin capsicum (O.C. pepper spray) into the paint I could legally purchase, and it worked great.* Something about the peppers in the spray that marine organisms, as well as people, aren't fond of.* Pepper spray is legally purchased as a less than lethal weapon, but you must really be careful when spraying it into your paint.* The fumes will keep you tearing up for quite a while.* In my former employment I used this stuff a LOT, but never on boats.* Nice to see it has another use.
