Marin's recent thoughts on painting a glass GB got made me thinking. I
am not going to run through my Awlgrip paint experience on my GB42
woodie of 14 months ago again because it has been posted here and in the
GB forum. I understand his thoughts on using the boat versus sweating
possible damage to a "perfect" hull, but some day he may will want to
paint the boat, even if just for a sale. The paint job you can do then
can be VERY good and inexpensive compared to the boatyard version.
I personally can't rationalize a dinged up hull, but that doesn't mean
keeping up a painted surface has to be excessively expensive.
I would strongly recommend NOT letting any boatyard have a lot of your
hard-earned dollars to prep and paint the boat when the time comes. For
that matter, don't let them have any more than lay day money while YOU
paint her. While I got away with doing my own boat for about $500, I DO
NOT recommend doing it from a paint float like I did (I was alone for 90
percent of the time too). That's just for idiots like me. I probably
would have paid $500 just for half the required lay days here (2 bucks a
foot per day - lessee, that's about six days, not including the other
haul and blocking costs).
Due to weather and having to go to work and waiting between coats to
re-sand, the whole job took me a month. I think I could have prepped,
filled, sanded, filled again, sanded again, and painted two coats in
two weeks in the yard with adequate scaffolding and no other help. With
a helper, I would cut that estimate by 1/3. With two helpers - one
half. Working from a homemade float caused some errors requiring extra
coats of paint (see bulwarks comment below), but I was sort of happy to
have more than the two required coats in those areas.
For a grooved hull like our GBs, the grooves turn out to be a godsend
when repainting. Just try to do a roll and tip job on a broad,
uninterrupted surface like the fwd bulwark areas of a GB to see what I
mean. Smooth-hulled boats have got to be a real challenge for roll and
tip jobs. I ended up with four coats of Awlgrip on both the exterior
bulwarks before I was happy, but each coat (per side) only took 30
minutes to apply and about 30 minutes to wet sand a day later if I
wanted to hit it again. The grooves in the hull proper provide a
defined area which lets you run down the hull one or two strakes at a
time. Hand-sanding the grooves with a bit of sand paper wasn't overly
tiring, especially after the first go-round with high-build Epoxy. Then
apply the two-part polyurethane paint of your choice into the grooves
with a barely wet brush a few feet ahead of where you are rolling the
paint. The rolling converter and thinners allow one to work the paint
for a relatively long time; so you can do it alone by "grooving" a
little and rolling a little all the way down the hull. Then ratchet up
a notch like and, like an old typewriter, run down the hull again.
The job is less daunting than one might think and thus easier to enjoy
knocking about in the boat afterwards than in a high-dollar boatyard
job. That said, my own job is better looking than either of the
previous two boatyard spray paint jobs I had done (we did all the prep
then too). Remember, high-build Epoxy filler is your friend during prep
and subsequent repairs.
One day, several months later, I had the boat out to bottom paint and
finish off the boot top when I got a side-long glance at the hull with
floodlights glaring at an angle off the paint. I noted an area about 4
feet long on two strakes that was a bit orange-peeled. I whipped out
some sand paper and about 3 ounces of paint and in no time had it glossy
as a new car. You cannot find where I did it - grooved hull advantage.
The thousands of dollars saved will go toward cruising fuel.
