maybe imaron?? or is that now considered old technology?? As another
thought, 
when I paint a car I usually add a catalyst to the enamel - I don't know
if 
this will cause the enamel inside a capacitor to harden or not, I've
always 
used it on cars (where it sure helps durability).  The only 2 part epoxy
paint 
I have used is a red lead primer made by dupont (name escapes me right
now and 
I'm 15,000 miles from the can of paint so I can't look it up) - clearly
one 
thing to be careful of is conductive additives.  If I was going to use
modern 
materials in this way, I think I would be inclined towards some form of 
silicone compound, perhaps one of the potting compounds used for HV 
electronics, if the drying time can be long enough to get the cap
assembled 
before it hardens too much  - there is a red silicone rubber compound
that I 
see used a lot to protect certain kinds of circuitry, but I don't know
it's 
properties.

On the other hand, the latest batch of two pack polyurethane paints or
even a good grade of epoxy resin, (as used in boat construction) might
be ideal for this kind of service as it not rely on exposure to air for
its cure.
