Joakim,

it's best to get samples and try for yourself.
Not all inks and papers like waterbased coatings.
And each of the myriad versions of Clearstar 
products has a very different effect and works
differently. 

Please also keep in mind that cans of Clearshield are 
marked with a date: try not to use anything older
than a year. The date is encoded (ask Clearstar for
help with this).
Also, you may find that the solvent based produces better
blacks. Application is a big issue too: it's best to
spray and best to apply 2-3 coats, but that depends on
the look you want.
The difference between the products is not likely to be
their archival qualities as much as how they "sit" on the
paper.
For smooth, even coating, a high-end laminator is better
for paper (but not for canvas),
assuming you use archival laminates that can melt into the
paper surface.
There is also a waterbased product from the UK 
(Giclee Varnish) that seemed to work better on paper
than Clearstar. It may be easier for you to find there...

Generally speaking, seeking higher dmax with coatings
is dicy. In some cases, its a lot of work for little
benefit. If you frame under glass, for example, you may
not see a big difference between coated and uncoated.
And if the sheen of the coat reflects light (glares)
you get less effective dmax than the smooth matte
surface of the paper. 

good luck - 

Antonis
