We built in 2005 and used SW Superpaint semi gloss on the Knockdown finished dry wall and Emerald semigloss for the trim. Just finished doing some touch ups last week in two bed rooms with a can of left over Superpaint on the walls. Carried it back to the store to have it mixed good and still matches perfect. Seal the can good and store it where it wont freeze, will last for years.
