Yeah, I've seen that site as well.
One comment I've read, from someone that used copperpoxy, is that you need to wipe down the hull at regular intervals. I wonder how effective no bottom paint would be, if you were already down there scraping it off every other week. Either way, I'm going to give it a try and, at least for awhile, it'll look like a shiny penny. How cool is that. :-)
: This web site is what I have been reading. Ten years between bottom paint jobs sounds good.
