Continuing towards my goal of
completing all the bulk sanding as soon as possible, I
attacked the bottom. I'd decided to simply heavy-sand
the bottom, rather than strip it: I could see no
justification for the extra time, effort, and expense
involved in removing paint that was minimally built up and
in generally good condition. If the paint had been
heavily layered, or chipped and rough, or in poor condition
and flaking off, I would have stripped it. As it was,
it was in good shape, and I am not too fussy about boat
bottoms. Good enough is good enough.
But in
this case, it was clear that the bottom had been stripped
not too long ago, and the new buildup was minimal--a few
coats only (2 or 3 layers of shark white, and a layer or so
of red beneath), and ablative paint to boot. In
addition, my earlier sanding tests had revealed the presence
of a barrier coat on the hull beneath the paint. Now,
I couldn't have cared less about the barrier coat, and
"saving" it didn't factor into my decision; rather, I knew
the epoxy would be more difficult to remove than the paint,
and again, lacking good reason to do so I chose in this case
not to do so.
Sanding was quick. There were a
few areas where the paint apparently hadn't adhered well to
the barrier coat (a common issue), and was flaking away.
I sanded these smooth and feathered them into the
surrounding paint as well as possible, but otherwise my
sanding chore was limited to just a thorough, heavy sanding
of the entire surface. Later, I'd remove additional
paint around through hulls I needed to patch, and other
areas that might require additional attention, but my goal
now was t get the heavy dust over with.
It was not a
particularly photogenic day of progress, but here are some
pictures of the sanded bottom paint.
