I respect Hunter fans, and they are always my first choice. We installed the Mariner in the Summer of 2010 in an outside covered porch that is open to the air but no direct sunlight six miles from the Gulf beaches in Englewood, FL.

Not TERRIBLE yet, but the white blades certainly stand out as WHITE and the rest of the fan looks almost light almond. I was somewhat surprised. I know the gulf air is hard on things, but we're six miles from the coast...not
