On "Changing Rooms" (the BBC version of Trading Spaces) they do something where they paint an undercoat (eg green). Then they rub a candle or other wax over the areas that would ordinarily take the most wear. Then paint with the top coat (eg brown). The places with the wax don't take as much, if any, of the 2nd coat of paint. They also use a fine steel wool to rub the edges that would take wear.
Is that the type of distress you're talking about? Or do you mean the type with dents?
