I did one once by using a brush about the width the channel and held a piece of note card along the inside to run the brush along and act as a shield. There were a couple places where I touched the outside and had to wipe it out. You have to keep a fair amount of paint on the brush so it doesn't look brushed.

If I had to do it again I think I would tape it up and spray. You could put the piece of tape at the bottom of the channel and run the inside fairly easily, the outside wouldn't be bad on the flat spots but you would probably have to do some x-acto work in the corners.
