Best Paint

Your contractor might be comfortable with a particular type of oil-based paint and is willing to stand behind it.  That being said, I
prefer latex paints since they are generally easier to apply, easier to clean the brushes and are easier on the environment.  When latex
paints fail, they tend to bubble and peel off.  Oil based paints get hard and chip and crack when they fail.  If your home gets too humid,
almost any paint will eventually have problems, however an evaporative cooler shouldn't bring the house beyond an acceptable level of
humidity.
