Behr is not a bad coating for the money, it is like any other brand made, they all offer some good products and they all offer some sorry products, One of the drawbacks in some of the behr coating is it's inherent poor hide in whites, this is not a fault of poor formulation, more like the fact that In order to acheive a very clean white, you must remove some of the shading that tends to gray or off set the whiteness of color. Behr also offers a "One coat Paint, these are generally shaded, and may contain a certain amount of clays to offer much better coverage, however a poor color selection. Unfortunately behrs problem is that it is not well liked by painting contractors because of the hide problems and the workability. The products were designed for consumers in mind, and that is why they are sold at the stores they are. Homeowners have very different requirements than professionals, and the "mere puffery" that is the warranty claims are what homeowners go for. It is bogus for behr or any company to offer so called "lifetime warranties" on products, especially the exterior coatings in general. Reality dictates that a top coating will get about 12 years before it is in need of repainting. This is a fact.
