Last five posts from the CHAT-M-Room (Town Common) are:

We seem to be getting off track re the paint shed. The posting was about All kinds of paint, there just happened to be some bottom paint there at the time. We have seen all kinds of folks looking for all kinds of paint. From the adult and child looking for enough to paint a birdhouse ; to someone looking for spray paint for a piece of metal yard furniture they just got at the swap shop to getting expensive mildew resistant paint for a single bath when they only need less than 2 quarts for their ceiling.

Yes, copper bottom paint is by design toxic. Men and women who work on the CG36500 have the advantage of using Festool Sanders, which when the sander is turned on, the vacuum turns on. There is a two-step filtration system; the vacuum sucks dust through the sanding disc holes.
Great machines, provided by a grant from the Boston Marine Society, the oldest such Society in the world.
And yes, I have heard of red pepper being used.
To remove all of the red copper based paint on the CG36500, it will take some effort before we can go to the newer stuff.( Captain Bob Ryder did the last removal job.) We will tackle that
with needle guns next season.

There are some excellent water based bottom paints now which are easy to apply and clean up is soap and water. Pettit Hydracoat is one. I've used it the last few years and it works great

Thank you Alan. The Some of the old timers used to add a little creosote to their bottom paint, claimed it worked very well. Others added ground red pepper to their paint. We did this one year with good results.[pepper that is]
Most people may not realize this but the Moderator has the right to bar the doors and order the police to stop people from leaving in order to keep a quorum so they can finish town meeting. We have been there when this was done but its been awhile.

About the subject of paint
Ablative red paint implies that the active ingredient is lead oxide which has been outlawed for at least 5 years now due to the high lead content. There is only one company in all of the USA who continues to produce and I guess with a waiver.

Most use Interlux products (the "blue cans") with copper which offers no improvement where the environment is concerned. And if you are involved with preparing your surface with sand paper, the dust coming off is brutal to the body. Protection is highly recommended!

Pettit (the green cans) actually calls out another ablative called "Econea"
which is organic and much safer, it has been on the market for about 5 years and yes it is more expensive, but it works without having to deal with copper.

The US Navy has been conducting studies with "Econea" to assist them with at least some of the copper used.
