No, you don't. If you paint directly on bisque,
it will be very absorbent, which can make it
tricky to get a flowing brushstroke, but keeping
the bisque wet will help. This will work for
using acrylic paints; probably not as necessary
for water-mixable oils. Regular oil paints work
fine on bisque clay, too. Paint will NOT work
well over glaze, so you wouldn't want to do that
anyway. That's not the kind of 'sealer' they
meant, unless you are planning to use china paint.
I don't recommend china paints for this. It doesn't
sound like a good choice for your intentions. China
paints are designed to go over glaze, and have to be
re-fired. If you put them over bisque, they will look
very ifferent than over glaze even if you fire them.
This doesn't mean you can't give it a try, but it
may not be the effect you hope for. If you have
china paints available anyway, do a small test
piece, but I think you'll be happier with paint.
All paints will go on more smoothly and
'normally' if you apply a coating of gesso first,
though. Just ordinary gesso from the art-supply
store like people use on canvas before painting
on it. It works on clay for the same reasons:
it makes the surface less absorbent and gives
it gives a smooth texture and a bright white
color which makes the paints look brighter on
top of it. If you don't use gesso, the color of
the bisque will tend to show, which could look
nice, or not, depending on what you want. It's up
to you, but it sounds like you might want a more
'finished looking surface, so go ahead and gesso
it, then paint it.

As daffy as this may sound, I often first brush a coat of milk on the
sculpture prior to painting. I find this creates a flowing
brushstroke when painting with acrylic paint.

At first I thought you were asking about painting an already bisque
fired sculpture with paint (rather than glaze), such as artist
acrylic or oil paints, which would not be fired again after painting.
If this is the case, you you can seal the clay surface with something
like an acrylic sealant, acrylic medium , rabbitskin glue or gesso,
or make some gesso using rabbitskin glue and whiting, and yes, even the
milk finish is a traditional finish.
however later in the post you refer to refiring the clay, so I
realized you probably are referring to 'china painting' which is fired
on, rather than 'paint ' painting,( which is sometimes referred to as a
'cold' finish, among other things.)
Once the clay has been fired to cone 04 or 06 you can refire the clay
to a lower temperature, such as cone 016, paper clay too.
I don't work with china paints, which are fired on, so can't advise you
on whether it is best seal clay before applying them , and what that
sealant would be.

What would be a good way to seal it before painting, and should I use

016, and can this low fire paper clay be fired to that temperature
