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.
