"I have been a painter for years and years. This paint is just what I needed from rental properties to high end work. This product works well straight from the bucket for ceilings and closet interiors. Haven't had any problems with tints from chopstick 7575 to deep grays.. The only color I have had a problem with is reds. Paint first with a light gray and the reds will do fine. I always spray or use an 18" roller.The flats do not holliday, the eggshells do not flash if cross block and the semis dry to a hard finish. Don't hold back, paint heavy using Purdy tools and you will do fine."
