I'm sure different epoxys will have different mixing results but the
website has good instructions on thinning but I didn't have to
thin. I applied it at a rate of about 360 sq ft per gallon. Two
coats made it a coverage of about 180 sq Ft per gallon.
It's not the best bottom coating labor wise because it will need a
light scrubbing every 90 days or so to get the scum off or the hard
growth will attach to that stuff. I opted for it because it's epoxy
and can set out of the water forever and not lose it's
effectiveness. Just a light scrub with a brillo pad to remove the
tarnish and your good to go.
I was curious how the copper could be exposed being imbedded in
epoxy but early this AM I went out and ran my fingers over the
finish. A couple hours later, the copper had slightly tarnished the
same as the bottom of a copper kettle reacting to finger prints so
it must be well exposed.

Jeff,
Thanks for that report. Where did you get your copper powder?

Next batch you paint, sent me a square and I will weight it and hang it
off the back of my boat for a test run.
Every thing I have read suggests that it will resist hard growths for a
loooong time but you need to scrub regularly for soft.

Today I coated both bottoms of the front section and the
cockpit section with copper / epoxy. I bought copper power and
mixed it with epoxy to come up with the home brew of
CopperPoxy. I mixed up a gallon since that's what the
CopperPoxy page said it would take to cover the two sections.
I measured out 2/3 gallon of resin and 1/3 gallon of hardner
into two large coffee cans and added the same ratio of copper
to each for a 3lbs / gallon mix. It seemed thin enough so I
added another lb. of copper This seems about right without
thinning the epoxy. The range is 3-5 lbs per gallon but I think
5lbs. would be a bit too much without thinning. I rolled on
two coats 6 hours apart and on the second coat, the copper
color really came out.
This is very easy to work with and the Very Slow hardener from
RAKA gave me more than enough working time in 85 degree weather
to mix and roll on about 16 oz. at a time.
A couple notes, this stuff mixes hard so a paint mixer is a big
help. I used coffee cans and the copper/resin is fine but the
copper/hardner got a dark tone to it. I think the
copper/hardner/tin can all combined and set up a reaction. It
did rolled on without discoloring and setup fine. Don't know,
maybe some chemist out there will know but I'm using plastic
jugs next time.
One more note, mix it constantly as the copper is much heavier
than the resin and will settle to the bottom fairly fast.
Over all I'd recommend this method to get $100.00/gallon
copper/epoxy rather than 4 times that amount at the store.
4lbs seemed about right too for the RAKA epoxy. Rolled nice
enough but don't use a brush, it doesn't work at all. To brush
I'd go to the 3 lbs. / gallon mix and thin it alot.
I'll post pictures next week on my site.
