Jeff,
for what its worth, Dick Arentz expressed the theory in a workshop I
attended that the first coat may just be acidizing a lot of papers that are
too heavily buffered - in effect, the same thing a much cheaper coat of
Oxalic Acid would do. I've done both and I think on some papers, there ^may^
be a benefit. But it's subtle. I think the OxA is the easiest and cheapest
trick most of the time.
