Just had the exterior of our home painted with Duration, too soon to give a report on but it goes on and covers nicely. Also, about to use in in our livingroom.
I selected it based on our experience with SW paints and their reputation. We use SW paints at our plant, and have always had good results.
Have not used BM paints for years, but they always had a good reputation. I have also had good results with MAB Seashore exterior paint.
