Since I'm not experienced with the type of paints you are using... that
would be difficult to advise on Wally. Generally I would try feather, paint
and antifoul... in that order. How thick is the paint or it's application
that would suggest the requirement for feathering? Maybe several layers of
thin, diluted applications onto a feathered surface will get the required
results.

It's not so much the feathering that's the question (I reckon three coats of
each), but whether I should paint to a little below the waterline first,
then antifoul on top, or antifoul a little above the waterline first, then
paint. I reckon paint first, then antifoul, but thought it would be wise to
ask.

I don't think there's a problem with the anti-foul going on top of the
paint, although I could try a little test first - I had originally just
sanded the old paint smooth to prep for priming, but, when I went to wash
the dust off by wiping down with thinners proper to the primer, I found that
the old paint was softening (so I took it back to the wood).

Old rule of painting... never apply a lacquer paint over an oil paint. The
opposite is just fine. If the thinner will thin both of the types of
paint... don't prep with thinner... use alcohol. Generally if the antifoul
is ablative it must go over the paint.

Would a 'marine' epoxy be a suitable material? One with 'thick' written on
the tin? (As opposed to 'thin and runny'.)

Good god.

Oh, should I get one with an irony constitution?

Aha! I'm aware of that (being a painter of pictures), but have no real idea
of what's in the boat paints.

I was thinking that the same stuff might be in the primer, which might lead
to the primer itself weakening the substrate. Still, the belt sander got the
old paint off in very short order.

It's described as a hard, self-polishing antifoul (which, I guess, means
that it ablates slowly). Aye, methinks I'll go for antifoul over the paint.
Thanks for the advice.
