If it failed it was due to causes as yet unrevealed, likely improper
application or inadequate surface preparation.

Perhaps, but the application and prep were meticulous. All treads and
risers were removed and thoroughly scraped, wire-brushed, sanded, and
brushed. Primed with oil primer all six sides. Top-coated with 2
coats of porch and floor latex all six sides.

So the other possibility is perhaps the conventional wisdom of latex
topcoat over oil primer is not universally correct for all
applications. FWIW, I spent 30 minutes in a paint store this afternoon
reading the label of each and every different exterior primer, both oil
and latex (8 or so different cans). Not a single one of them listed
exterior wood floors or steps as an acceptable application. Some of
the highly-touted brands such as Zinser 123 and Kilz explicitly
excluded exterior wood floors and steps.

It will take a couple of years, but my experiment with the backyard
porch steps should be most interesting:
