Following my previous thread about painting an MDF shelf, all of the
preparation went to plan. I used oil-based primer and full undercoat.
I am now applying [oil based] eggshell as the topcoat.

However, even after about four coats, the topcoat remains uneven. I
can think of two possible explanations:

1. To try to do the job with only one brush, I used a 12 mm brush. I
think the paint may be drying too quickly to allow me to achieve an
even finish.

2. I found the paint in the the garage and it is quite old (though I
cannot see anything wrong with it). I stirred it thoroughly and there
is no significant residue at the bottom.

I wondered about any comments from the experts here.

How wide/long is the shelf? Anything bigger than A4 and your not
going to be able to get enough paint on thick/fast enough for it to
"self level". Gloss painting is a bit like plastering (without the
polishing stage), Whack it on, spread it out to stop runs, couple of
strokes to smooth over and LEAVE IT ALONE.

(*) Possibly becasue it covered so well I followed the above better
than I normally do, particulary the leaving it alone.

MDF fibres will be raised and need rubbing down between coats to flatten

I did that. The main problem is a patchiness in the finish
corresponding with each time I recharged the brush.

That would appear to be the answer. I certainly didn't fancy trying
to clean a roller using white spirit.

The mini foam rollers are handy. If you need to stop painting for a
period (up to a couple of days) then don't bother trying to clean the
roller, just tightly wrap up the business end in a large plastic bag -
that will keep it "wet" until you next need it.

I use cling-film. A couple of layers will keep the brushes moist for a week.

Sounds to me like you need to thin the topcoat a bit. And definitely use
a wider brush.

We used to do so in them good old days when rollers were really made proper

I remember the first time I tried that (with a full size roller). It's how I discovered that some rollers are in fact made from card!

Super cheapo one?

In decades I've never come across one made of card...
I can't think of any advantage of making them from card...

One can also stick the foam roller in water ... load it with paint generously,
stick it in, take it out later. Any water that doesn't shake out will form a
drop that sits on the wet paint, and a rag will pick it off easily.

Does this work okay with oil-based eggshell?

the white spirit probably cost more than the roller and paint combined.
If wanting to use the roller again, say within a day, wrap it in cling
film or a plastic bag.

Also, sometimes depends on the paint. I used a foam type roller for
some Zinsser "sealer" paint, wrapped up the roller and a couple of days
later when wanting to use it again the foam had disintegrated. I also
noted with this type of paint when washing the brushes in white spirit
and then storing the spirit/paint for reuse the pigment appeared to stay
in solution without settling to the bottom of the container as it does
with most other solvent based paint.

The trick I've seen is to get it on fast with a roller and then use a
GOOD Quality wide brush to go lightly over once to even out the paint.
The technique seems to rely on getting the paint on very fast and not
over working it.

Yes, I suppose of water and oil do not mix the water could provide
better protection that white spirit would. I hadn't though of that.
