TWL: Antifouling Spray....
Folks, I've looked in the archives unsuccessfully....maybe someone
remembers. Some while back there was a conversation about some sort
of antifouling spray that someone used on the underwater hardware on
the boat.....props, shafts, rudders, etc. I seem to recall that it
contained graphite, among other things. Does anyone recall this?
Could you point me toward the right place in the archives? Thanks
much.

John, I don't know my way around the archives but keep some
interesting articles on my own disks. Here is what I've got on the
permanent bottom paint. Hope it helps. George of Scaramouche....

Subject: New bottom and propeller coatings
I ran into a guy this morning who was putting a very strange bottom
paint
onto a boat, made by Belzona. It was about a 45 foot sport
fisherman sort
of thing, and very nice. The bottom paint was very smooth, hard, and
shiny. I got to talking to the engineer for the company who sold the
coating, who happened to be on site. He says that he has put it onto
the
bottom of several cruise ships, and is just now looking at the
smaller boat
market for his product. He also had a similar coating for
propellers,
which is supposed to prevent damage due to cavitation. He says that
he has been
using it on industrial pump impellers for years, and has only
recently
began marketing it for marine propellers. It enables you to select a
propeller
that cavitates all the time and not worry about it. That would be a
huge
advantage in selecting a propeller. He says that he re-coats them
every
5000 to 20,000 hours, depending upon application.
The bottom coating was unlike any I've ever seen. It is not toxic,
so it
does not kill the growth. It is not ablative, so it never needs to
be
applied again. It is very slippery, so that the growth that
attaches to it
at the dock falls off when the boat begins to move. The idea is
that this
is a one time application, after which you can forget it. Frankly,
it
sounds too good to be true; but certainly worth checking into.
from a friend who is the BELZONA rep for the Annapolis area:
Belzona products can be applied by just about anyone since Belzona
provides
free technical assistance after you buy the product. Surface
preparation
must be in strict accordance with Belzona Instructions for Use but the
products are very easy to apply even under somewhat adverse
conditions. In
the Chesapeake Bay area around Annapolis I have applied Belzona 1341
Supermetalglide to the shafts, struts, props and trim tabs on my
Post-46
Sportfisherman with very good results. The props bite better and I
noticed
a slight (about 6%) increase in speed. Barnacles do grow on it but
they are
rather easy to remove with a gloved hand or plastic scraper while the
vessel
is in the water. The same results were noted on a Grand Banks 42 and
several others. There are many other products that they make that are
useful
to anyone owning a complex system such as a large boat. Belzona has
been
around for about 45 years and sells to the utilities and merchant
marine
industry primarily because of the relative cost of the products.

After we put bottom paint on the bottom of the boat, we spray our prop and
shaft with teflon spray. You can get it at the hardware store in an aerosol
can. We have used it for 7 or 8 years and we have NEVER had one barnacle.
Our neighbor said "I've got to see this." and, sure enough, when we hauled
out a few weeks ago, there were no barnacles on the prop or shaft.

John,
I remember someone mentioning the original formula of NeverSeez grease
from Bostik. The thinking, as I recall was because it contained copper.

John,
On the recommendation of a local boatyard I have been
rubbing Desitin ointment on the prop and shaft of my Grand
Banks 32 during the annual haulout. It does seem to keep
the barnacles off.
Desitin is intended for use on babies' bottoms and consists
primarily of zinc oxide. You can buy it in a drugstore.

Anne,
Sounds like you are the answer to my prayers, er... the spray that is.
I didn't think anything would stay on the underwater hardware and
continue working. Can you be more specific about exactly what this
teflon spray is? Brand name? Intended use? Did you do anything to
prep the prop before spraying.
I must get some quickly before Paul Browne buys it all and put it on the
shelf with the Cheyenne... I mean Cayenne pepper I'm stocking up on.
Thanks again,

Mel -
Bob looked in the West Marine catalog and found "Super Lube" Teflon. You
can get it in the spray or in a tube. The spray is less messy. After
spraying it on, he makes sure the prop is covered by rubbing it all over
with his hands to make sure he didn't miss a spot (the prop that is). Make
sure you put your zinc on first and not after you have sprayed the shaft.
Don't know if it makes a difference, but that's what we do.
We just use the cheap stuff from Best Hardware here in P.T. One brand is as
good as another. It is made as a lubricant. Shhhhh, don't tell Paul about
it. He will try to put it in the paint with the pepper.
PS I thought you had to go to Wyoming to buy "Cheyenne" pepper.
