Bob-
My HP 450 uses the 57 cartridge, so I'll definitely look for the plus version.
One problem I've had, is that the 57 ink has almost zero resistance to
water, no matter how long it has dried. Do you know if the 57+ is any
better in that department?

HP Vivera ink is unlike the Epson DuraBrite ink; it's not pigment
based, but is chemically formulated, along with the HP Premium Plus
Photo Paper, to sink and lock into the paper so that it's actually
underneath the gloss coat (not entirely scientifically accurate, but
close enough). This lets them claim the longevity that they attribute
to it. I'm not sure how this would affect the waterfastness. Using it
on plain paper or with another brand of photo paper would be the same
as any other dye ink.
I doubt anything that comes out of an inkjet would be what most people
wold consider 'waterproof'; I finally gave up and had my bumper
stickers laser printed onto waterproof labels. Onlinelabels.com
carries an 'inkjet waterproof label' that supposedly 'encapsulates'
the ink. This would still not be fade-resistant unless you had pigment
inks (which might not even work with it). Office Depot also makes
'waterproof bumper stickers' but the old packages of them used to say
something about 'take them off if the car will be exposed to heavy
amounts of rain', I don't see this on the new packages. As someone
else also said 'HP Advance' paper is supposed to be water resistant
with all HP inks, but it's pretty thin, 20 lb.
