Give Kevin a break, he's young and only learning the trade. Getting black from head to toe is a learned skill. It's one of those macho sort of things. By the time he's done a few of the jobs described, he'll have the knack. And it is also reasonable to assume that he will not be let into the house until he has shed everything but his underwear. I have never really done it well, but even some of my works duds show the signs of too much bleach....I mean basically,if you get the grease out of the duds, there's not much left to wear.
