Ask the painting contractor chickie.

I've been a painting contractor since 1979, with forays into other ventures along the way. I have painted shopping malls, Victorian mansions, new builds, striped parking lots, thousands of homes and businesses, freeway retaining walls and underpasses...pretty much anything that stands still long enough to be painted. I've run crews and been a foreman (forewoman, I guess) and taught many people the craft.
