@Jann3 - YES! I am a giant supporter of Sherwin Williams paints. They are not cheap, but the quality of the paint is so much better than the cheap stuff you get at the big box home improvement stores. It's what professionals use for a reason. When you have to buy 2 gallons of the cheap stuff to cover a room vs. one gallon of the expensive stuff, you really aren't saving money, plus the extra time it takes you to do the job twice.
Fun Fact: The Golden Gate Bridge is painted with a proprietary Sherwin Williams paint. The paint had to be specifically formulated to withstand cracking, peeling or stiffening the structure so that the suspension brige can freely swing during an earthquake, in the wind, and doesn't need to be repeatedly repainted due to the water spray from below. It's really incredible the science that went into that paint. Also, the color of the bridge is copyrighted too, only that bridge can ever be that color 🙂
(full disclosure, I did work for Sherwin Williams at one time but do not own stock or have any interest in their success)
