Default Bottom Paint Half Price (Serious Question) RESULTS

This makes more sense to me than those post who talk in terms of years
without haulout and paint so they put the stuff on much thicker.
Here in Norway I have to haul out every year because although Oslo fjord has
never frozen right over-at least since I have lived here-the channels
between the inner islands do freeze in a bad winter and the small creeks
where my marina is freeze every year and I do not want to see my boat iced
in with a couple of feet or more snow along the pontoons and no electricity
or water available at the berths.
So I haul every year and give my boat one coat of Hempel antifouling which I
apply with a brush and she always comes out clean except for the propeller
and shaft.
I have not found a rally good solution for these last because the speed of
rotation soon takes off the ablative coating of a standard antifouling.
However, I have found some antifouling Volvo sell (very expensive) in a
spray can for their outdrives which works pretty well because (I think) the
fouling cannot adhere to it and as soon as you run the motor it mostly
shears off.
I always use a brush. I do not go with rollers because they may be OK for
the wide open spaces but you will have to use a brush at some point for the
awkward corners. I never clean my brushes. Just squeeze off the surplus and
leave the bristles nice and straight and let them harden like that . Next
year soak them in gasoline overnight and they come soft again as antifouling
just washes off in gasoline.
I have a 38' fin keel boat with a spade rudder and the whole job takes just
four 750ml tins each year.

Good point about the gasoline/petrol. Its a lot cheaper than thinners
for equipment cleanup - even at UK rates of duty on road fuel - and does
a good job on roller handles and brushes. I usually do the cleanup in
the old roller tray and that gets clean enough to re-use as well.

You would be surprised how much of an average hull you can sensibly do
with a roller, and cutting in round skin fittings, anodes etc. is easier
with a 1" brush than a big one. Why not wash out your brushes BEFORE
they set rock solid though?

I've been using a red lanolin based grease called 'Propshield' on the
propeller and it's better than nothing as it keeps the fouling from
sticking hard so it comes off with a pan scourer. The propeller
manufacturer recommended NOT to use paint as they reckoned it increased
the risk of electrolytic pitting.
