I really don't think you guys are making a fortune at $35 a pop Fast.
I think since the state and some local agencies have tried several times to institute copper based paint bans, it would not surprise me to see an "end run" by those concerned.
It does not seem unusual for government and others to institute regulations that are unworkable for all concerned. For example, if they ban in water cleaning, owners have no reasonable alternative, divers and others are negatively impacted to the point of desperation. So, in a month or so the regulation is dropped in favor of a copper paint ban and it suddenly becomes a moderate compromise that sounds better to all involved. Maybe it's a little paranoid but a quick look at the studies says only non-biocide paints produce zero leaching, so it seems this might just be an attempt to gain more support for banning copper.
