Second: all the tricks of the trade in regard to "cheating" customers is for hustlers and cheaters and NOT established businesses. At the end of the project the job should come out looking professionally painted as specified in the contract. A selected color that takes multiple coats that was not calculated by the contractor should cost more money. It's not the fault of the painter.
A good paintbrush is key to a professional-looking finish. "A quality brush costs $15 to $25, but you'll discover that pros aren't as talented as you thought," says Doherty. "The equipment has a lot to do with their success." Most of our pros prefer natural-bristle brushes for oil-based paints, but they recommend synthetics for all-around use. When choosing a brush, pay attention to the bristles. Synthetic brushes are made of nylon or polyester, or a combination of the two. Poly bristles are stiffer, which makes them good for exterior or textured work, but for fine interior work, Doherty uses softer nylon brushes. Look also for tapered bristles, which can help you work to an edge, and flagged tips, which help spread the finish smoothly and evenly. Brushes are available in 1- to 4-inch widths. Most painters keep an arsenal on hand to match the job. "Use common sense," says Maceyunas. "A smaller brush gives you more control, but no one wants to paint a door with a 1-inch-wide brush." Doherty recommends starting with a 2- or 2-1/2-inch sash brush. The angled brush makes it easier to cut to a line and puts more bristles on the work than a square-tipped brush.
