My medicine cabinet door w/inset mirror project is coming right along.
The door frame, which will hold the mirror, is built of poplar w/45
degree miters, joined with biscuits and glued with urethane glue. It's
not fine woodworking but once painted it will look all right. Hey --
it's square, flat, feels solid, and will fit the cabinet. I take my
little victories where I can.
One of the joints didn't close completely and needs a bit of filling.
The gap is no more than 0.02'' wide and half that deep. I have "Plastic
Wood" and that lightweight white spackling compound on hand. But this is
such a small gap that I would not expect either to sit down in it real
well when I go to finish sand before painting. What's a good filler with
strong adhesion for filling a small gap like this?

You may be able to just burnish the gap shut. Use a smooth
screw driver shaft, chisel neck or the like and rub each edge
towards the gap. If you're careful you won't round the
mitered corner line noticably.
I have used Minwax "advanced" wood filler to
fill small (or even larger) gaps in painted projects.
It is a two part filler that dries rock hard in about
20 minutes or so. It's around $5 or so, but you get
a large amount so you can have it for other
projects. Once sanded smooth, the gap vanishes. I like
it because it doesn't seem to shrink like some others.
Miters always drive me crazy for some reason. There
always seems to be a small gap here and there.
I've used a product called PC Woody; it's a two part, sort of epoxy like
filler. I used it to fill in some areas in window frames that had dry-
rotted over the years (cleaned out the dry rot, first, of course).
This stuff worked really well - good working time, filled with no
shrinkage, and was pretty easy to work with after.
I painted over it, and you can't tell the difference between it, and the
surrounding good wood.
Got it at the local Ace Hardware ...
In general, probably nothing.
In my case, I had a number of corner areas to do, and wanted something
easier to work than regular epoxy, yet stronger than "bondo"-like
materials (eg, regular wood filler, spackle, whatever).
This stuff fit the bill -- good working time, easy enough to sand
afterwards, and no issue with paint adhesion. (The mfr claims you can
sand, drill, or plane the stuff. Dunno that I'd want to plane it, but it
was very workable ...)
Of course, YMMV.
Just take the sawdust from sanding and mix it into a paste with white
or yellow glue. It gives you good color matching, which in your case
isn't that important since you are painting. However, this is my
preferred filler for most times I need a filler and want a close match
to the wood I am using. Whenever I empty my belt sander bag, I just
empty it into a zip lock bag and keep the sawdust until I need some
