My Granny always said there is no stupid question. Well Granny dear you may be wrong this time. My Chinese neighbor comes outside and asks "Why you no keep the gutters red?" I'm like excuse me. She asks the question again. Then she tells me it so pretty. I'm like because the contrast sucks. "Me no understand". So I explain that the red is primer. It helps the paint stick to the metal. But all she cares about is that the red is so pretty. Here are a few pictures for you to see.
