Whether it's a modest touch-up of the guest bathroom or a complete redo of your cathedral-ceiling living room, the right tool for your next paint job can go a long way in determining the end result. You may say, "It's a brush, how hard can it be?" The answer lies in this simple analogy: the difference between an adorable finger-painted masterpiece and an exquisite watercolor of your favorite scene. Given all factors being equal (skill, age, paint)--the tool--makes all the difference in the world. And while we love finger paints, sometimes the job calls for a more precise application.
