Chris, you say "they thought" -- I daresay some folks may have thought
that, but I don't recall reading it... or at most once. And there have
been many writers who suggested multi-coats, from Heinrich Kuehn & that
other Austrian whose name I don't think of this minute, unless it's
Wurzel, which I don't think it is, to even our hero Paul Anderson, who
suggested 3 coats as standard, probably as early as his first book

I'll add BTW that even among us smart people nowadays it has been found
that a subsequent coat *can* soften a layer underneath, as was discussed
on this list circa 1998... and as I myself have encountered. My theory is
that it might have been more frequent early on when dichromate saturation
was generally less... tho who knows, it could have been anything.
