Duration is my best friend. It's so silky smooth to apply, gives good coverage rates, hides great, and leaves a durable finish. Speaking of silk....I swear the satin makes it look like you painted the walls with the finest silk. Most of all, customers really love it. Only drawback with duration is the stupid plastic can it comes in, lol. If you can get past dealing with a screw on lid that sticks (HELLO) once paint gets on the grooves, you'll be happy. I've used all varieties of paints, and this one is by far my favorite for interiors and exteriors. Having a lifetime warranty to pass off to the customer offsets the price easily. :Thumbs:
