I understand what you said. I just was curious whether it was actually
confirmed by the car itself. I apologize if you took offense. None was
intended.

I guess one more try.
The P-S cars that had stainless sheathing had the sheathing attached
with clips. It wasn't welded to the side, it was simply an
applique. With that type of attachment, especially when the
attachment is on the flat, versicle car side, you will see water and
other fluids run down and under it. By the time the Q received
their cars that originally had sheathing of this type (from the
C&NW), the sheathing was gone.
THE ROUND-UP on the other hand, was sheathed completely in stainless,
which means that the shot-weld process was used to attach the various
panels to each other, and the panels themselves were welded, not
clipped, to the car side and ends. If you look at a stainless steel
car, it is (essentially) one unit from the bottom of one side, to the
other. So liquids can't (usually) get in behind the stainless
siding. When the unit is basically a one piece shell, water can't
get under it (easily). In order to get under this sort of
construction, fluids typically get in via the windows or other body
openings. If the shop is careful, and the openings are done with
care, and sealed after, the possibility is a lot less.
Compare that construction with the Wabash-built "stainless" cars (one
of which was the Busch PV). Those cars were sheathed but not
welded. The result was a (relative to THE ROUND-UP) failure, as
fluids got behind and the cars were in less than optimum condition
relatively quickly.
The Q's Aurora shops were one of the more - if not the most -
proficient railroad shop in working with stainless. They had already
rebuilt several cars that would otherwise be totaled, built the
pattern domes, sheathed the Zephyr backup Hudsons, and generally
could do as well as Red Lion in terms of construction with
stainless. I haven't heard of the pattern domes leaking, if any car
the Q made would be susceptible to that, it was these cars (due to
the location of the cuts (roof) and the flexing of the car in that area).
