I've been out of the paint sceen for awhile so someone can give better detailed answers but a actaul satin paint would hold up better.Just black primer will fade and "chalk up" and evantaully ware off.The "flatter" the finish the less protection it has.Think of it this way interior house paint:Flat-you cant wash.Semi gloss-you can wash but be carefull.Gloss-is the toughest of them all and more durable.
