I have done very little work with oil-based paints, having focused most of the
last 27 years' work on masonry and concrete substrates. What work we have done
has shown them to be inherently UV-unstable, typically chalking as they
weather when properly applied, and peeling when applied to inadequately
prepared surfaces (Required: Sanding to a depth below the level of UV
penetration and degradation of the wood fibers). They apparently can be quite
useful as wood primers, but that still doesn't get you off the hook for having
major fights with your painting contractor over how much sanding is enough.
If I were itching for a fight this morning I would compare wood to vinyl
siding, as both are UV-unstable substrates, and would ask where in an oil-
based painted wood envelope was there anything that was going to endure
without all kinds of frequent maintenance? But I'm not, so I won't say that.
