You're right, on all counts. I've been looking at the job and
just tried some left-over Kilz spray on a scrap bit of MDF.
It seems to take very nicely. Looks like it will take two or
maybe three very light coats to avoid runs (which I hate).

Maybe I can find some not-too-smelly spray enamel. The Kilz
I had doesn't smell too bad.

Still pondering the preparation. The surface needs some serious
cleaning -- TSP I guess but without getting the MDF too wet.
Very light sanding I think -- too much will probably be
counterproductive with MDF. And a wipe down with mineral
spirits.


Clean it out with water and household cleaner, dry quickly. Sand when
dry, vacuum out the dust. Wipe with denatured alcohol to degrease.
Prime bare spots. Two coats of alkyd semi should be very easy to clean,
unless the surface is extremely rough. Keep cabinet open and ventillate
well with fan. I waited a week when I painted inside kitchen cabinets,
only because of the weight of dishes stored there and didn't want them
to stick.
