  We review an exact WKB resolution method for the stationary 1D Schr\"odinger
equation with a general polynomial potential. This contribution covers already
published material: we supply a commented summary here, stressing a few aspects
which were less highlighted before. As some of our earlier papers needed later
corrections, we also recapitulate these here in footnotes in the bibliography.
The latter, not meant to be exhaustive, focuses on narrowly relevant works plus
some broader ones that do offer more extensive bibliographies.
