From reading the blurb it sounds very much like "Copper Bot" that (I
believe) was originally a British product and consisted basically of
copper powder and epoxy resin. I believe that the original method of
application was to mix the copper and epoxy and paint it on. Later
systems (again I believe) applied the resin and when it got "sticky"
somehow applied the copper powder.

My understanding is that to be efficient the bottom had to be
vigorously scrubbed at periods to uncover new copper.

I have seen only one boat that had it applied and apparently it is not
a popular system.

The photo in BoatTest showed a blowtorch with a large flame being used to
heat the paint which had been sprayed on. It sounds different from what
you're describing. However, I'd love to see a 4-5 year bottom paint!

Sounds wonderful. Will it work well? Who can say? I wonder how you
'anneal' something onto fiberglass.

The December 07 issue of the UK's Practical Boat Owner has detailed
information by the Editor on copper treatment on her own boat that has
lasted 14 years.(pages 6 & 7)

Doesn't seem to be "annealed" or the like but it's stayed on for 14 years so
it's sure stuck to something.

I suspect that is the "copper Bot" I was talking about. I used the
"Copper Bot" name as I believe it was the first system sold.

Out of curiosity, does the owner mention that she has to scrub the
bottom occasionally to uncover new copper?

As an aside. I saw a long slim motor sailor, designed and built by
Sonny Levi (I believe the last boat he owned), in India that had
copper sheet applied to the bottom. It did have some growth the last
time I saw it but Sunny said that you just used a scrubbing pad and
hired a guy to scrub the bottom - no scrapping. Costly though I
reckon.

=======================
She refers to it as "Coppercoat" with a capital. Apparently, its original
incarnation was Copperbot and its had a name change, though the same company
still makes it. She does mention other disastrous products and I think I
remember one a couple of years ago in the same mag which attracted marine
growth - litigation all round etc etc.

==========================

========================
She said it was recommended but in 14 years she and her husband had never
done it.
========================

She does talk about a small experiment they did on the rudder, painting
three distinct stripes of antifoul x 2 and copper - regretted doing it as
they had to keep renewing the antifoul but never touched the copper.

Copper Bot sounds like the Coppercoat I saw in an article from
Practical Boat Owner p. 6, No. 492 Dec 2007 which states that the
editors boat hasn't had the bottom painted or scrubbed in 14 years and
has only just got some growth on it. It is in the water all year
round. Then it only need a scrub from a pot scrubber to revitalise the
copper.

Yes, I came across the December copy of Practical Boat Owner the other
day and bought it. After reading the article mentioned by another
poster it seems that this system was marketed as CopperBot initially
and later changed its name to CopperCoat with no appreciable change in
produce. It is still a two part epoxy shipped with bags of copper
powder that you premix and apply.

I did locate a vendor here in Thailand and, whether it is typical or
not, the cost in Thailand is approximately US$ 166/Ltr. with four
coats recommended.

Initially it causes a bit of a shock but if you divide the price by
ten, or more, (years of use) it begins to sound better.
