Over the long weekend I primed the inside of the shop,
two coats of PVA primer/sealer that had been tinted white.

This caused a stir at Lowes, apparently no one had ever requested
the already white primer be tinted white, basically they humored
me to get me out the door.

After two coats of primer (25 gallons) blocks are sealed and
no color bleed through anywhere, something of an achievement
when painting block walls.

Considering that I will most likely never paint the inside again,
what would be the best topcoat? Oil base or water base?
I am willing to spend the money for a quality, durable paint, but what
brand and type does everyone like?
Sometimes spending a lot of money doesn't guarantee a good product.

Considerations on applying in high humidity? Humidity is in the 90's
and will remain so until mid-September.

Whatever brand, I want to stick with white and at least a semigloss,
even considered a gloss or high gloss, but I have never seen that much
wall done in a true gloss, would it be too much of a good thing?

Everything will be rolled and brushed

I'd stick with a latex on concrete because it can breath better than
an alkyd. Alkyd modified 100% acrylic latex like MooreGlo should work
over your PVA primer. Check with your B-M dealer to be sure.
