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.
