SW Duration over Superpaint?
So for repainting my house a while back I bought a bunch of Sherwin Williams exterior latex Superpaint that was on sale, and also a gallon of exterior latex Duration, both satin finish. My question is I have used up most of my Superpaint yet still have this gallon of Duration, can I apply the Duration over a single coat of Superpaint? If its ok do I need to sand the first coat to rough it up a bit for the Duration to adhere or is sanding overkill?
