I personally use Valspar from Lowes. Its very good and have never had a problem with it. I work as a painter and home maintenance and have never heard of weeping wood. Although I did paint some wood on the exterior of a house the other day amd had to go back and paint over some knots in the wood that were showing through. Never happened, and very weird. As far as paint goes, always use a semi-gloss or gloss in the bathrooms. This helps when wiping the walls and if the walls sweat, they can be wiped down.
