Are there any tips for getting the best possible result with paint,
i.e. maximum resistance to damage from condensation?

Have you talked to anyone at a dedicated paint store - not a big box
paint counter, but a locally owned business that has been around for a
while?

I've had so many instances where the big boxes and the kids at the
national chains (Sherman-Williams, etc) knew less than I did about
what I was trying to accomplish. However, there is a small local chain
that's been around since the 80's as well as a family owned single
store (that I'm pretty sure sold paint to the pilgrims) where I can go
in, they understand what I am trying to do and offer suggestions that
make sense.
