Most people know that it is often the little details that take the longest, but yield the best looking finished project. No one likes to tape before painting, it is tedious and time consuming. However, it gives you a clean line that that will make your project look crisp and professional.
When you tape and then use a brush to paint you can still get some bleed over. I have found that the absolute best results come from using a sprayer. I use a type of sprayer that is called an air assisted airless sprayer. This device combines the best characteristics of air and airless sprayers, and it offers the best qualities of both types of devices.
Check out the photos below to see how clean and professional the paint edge is when you use this method.
