Other than a cheap latex paint, the brush drags rather quickly with the new non odor formulations. Painting outside in the sun or a hot day is very frustrating. There is no going back and brushing out a painted surface. For oils, you need to wet the brush first with paint thinner before dipping into the can. Thinning oil (mineral spirits) and latex paints(Flood's Flowtrol) is the key with the new EPA formulations. Also, to clean up oil paints, soak in thinner and brush out on cardboard or wood scraps. When most of the pigment is out, use dish detergent and warm water. Squirt the soap down into the brush, massage vigorously, then add warm water and work out the soap. Takes about 2 tries and you have a very clean brush.
