Thomas:
I agree with Alan. The o-ring seals by being properly 'squeezed' between
the hub flange and the axle flange. The paper gasket is there basically as
a dust seal - if you coat the paper with a sealer, it could move the axle
flange outwards just a hair - hence the possibility of a leak at the o-ring.
Make sure that they are the correct thickness, and put them on dry.
As Alan suggests, it's probably a good time to change the hub seals, but it
can be a pain - one of the hub nuts is a reverse thread - the hub bearings
have to be removed and re-installed (a press is best) - in the true British
fashion of the period, the seal is 'under' the bearing, etc. If there is no
evidence of diff lube on the back side of the hub, or on the outside of the
brake backing plate, or the shoes / drums, you may choose to defer the hub
seal replacement until a problem develops - the job can actually be done
without draining the diff oil - done it a few times!

Thomas -
As long as you replace the paper gaskets with pre-made
paper gaskets (don't make these yourself), and replace
the o-rings... and keep everything clean... you
shouldn't get any leaking. I would not use any
sealant or anything like that... it may not hold up
over time.
What you should do is consider replacing the hub oil
seal, that's where alot of the leaks come from ...
it's a little bit of a hassle, but a cheap repair well
worth it.
Cheers,
Alan
