I tried the Interlux Micron CSC this year, and have had good
results. Back this spring in the "how smooth is smooth enough?"
note somebody mentioned that the old Interlux 33 wouldn't quite
last a full season and the 44 worked well but would rub right
off if you touched it. Micron CSC appears to be formulated
just about like the old 44.
Back sometime in July I noticed just a small amount of slime
on the rudder extending about 4" below the waterline. It wiped
off easily, but so did the paint!
A couple of weeks ago I took a dive to look underneath and it
looked very clean with the exception of about 4" on the
rudder, which could use a little more paint ;)
All in all, I'm very pleased with the results.

| Club Wine was done with CSC in early April and has been used very
little this year (moved house instead!!!) but the results so far
are encouraging. Last year there was quite a build-up of slime
and algae after a few weeks alone in the marina, and this year is
certainly no worse (last year I used cruiser copolymer TBT). the
only complaint I do have is that the blue line of exposed antifouling
that sits out of the water clashes with her deep maroon hull colour!

| Life without TBTF is greatly improved, for the barnacles. For the
first time I've actually had barnacles growing on the bottom that
could not be removed with my long handled nylon scrubber. I usually
clean every week and what little growth occurs comes off easily.
My usual routine had little effect this past weekend. Frustrated,
I jumped in and tried to clean the barnacles off with a hand scrubber.
Despite the unusually warm weather in New England this summer, the
water temperature doesn't seem to have gone up one bit. I got about
three feet of hull done before hypothermia set in. Had to drive
all the way home with the car heater on high to stop shivering.
Returing the next morning with a divers dry suit, which leaked,
I resumed cleaning but ran out of time and energy. The boatspeed
problems we had during the race that afternoon indicate that more
cleaning was needed. An identical boat moored next to mine has
its bottom painted with some TBTF based paint that the owner saved
from last year. He was cleaning his bottom at the same time I was
and encontered no unusual growth. He finished ahead of me in the
race too.
In the absence of a breakthrough in biocide chemistry, it looks
like the only substitute for TBTF is going to be a wet suit and
weight belt.

| How ecology minded are you? My local lumberyard sells a mildewcide for
use in exterior house paint. The label says it contains TBT. Methinks
that an unethical person could create a more effective bottom paint than
can now be purchased at your local chandlery. Mind you, I haven't tried
this approach.
Has anybody else tried using Starbrite Compound X in his/her bottom
paint? We used it this year (in the same paint we used last year) and
there seem to be less slime on our bottom this year. Not exactly a
conclusive test, however.

| 970.5 | My Expereince with Micron CSC | SALEM::MCWILLIAMS | | Thu Oct 13 1988 09:16 | 37 |
| Well we hauled Freudian Sloop last week, and here's what happened for
the season;
This spring I over coated the TBT loaded RULE GRAF-COTE with Micron
CSC, after sanding down the GRAF-COTE. I was worried since the Micron
CSC has a warning about over coating graphite based paints. Several
calls to Micron's maker yielded a lot of conflicting information,
(their technical department really wasn't that helpful), but the
consensus was that since GRAF-COTE was a hard finish, there shouldn't
be too much of a problem.
When she came out there wasn't much slime on the bottom that was
painted. The boot stripe was a mess with weed, even though I scrubbed
it twice during the season, but that was probably because I was up
before the no-wake zone and was getting a lot of wake and wave that was
keeping the boot stripe wet, thus promoting growth.
I had complete erosion of the paint at the bow from the waterline down
about 8-12 inchesand back about 6-8 inches. Micron CSC warned that the
paint should be applied heavily to leading surfaces, and it seems
that 3 coats weren't enough. (It should be mentioned that I moored
in the Merrimac so there was always water moving past my bow).
On the port side about 6-12 inches below the water line and three feet
from the bow I had three patches about 8 inches by 4 inches where the
adhesion of the Micron CSC completely failed, and it is missing. This
area could be where the mooring ball rubbed against the boat at tide
changes, but it is also interesting to note that the GRAF-COTE below is
also completely missing - so it could have been an adhesion failure.
To sum it up the bottom looked as good or better than when I used the
GRAF-COTE. I will have to coat the leading edge of the bow much heavier
than I did last spring. The places where the paint did not hold well I
will grind down and recoat and hope for the best.
