Using a brush on an exterior surface has a lot of disadvantages. For one thing, the uneven surface from the brush strokes leave places for water and dirt to accumulate. This causes bacterial growth that attacks the paint and the under lying surface.
When you spray the surface, you end up with a coating that is less likely to trap particles and will reflect the harmful UV rays from the Sun. A rough surface will absorb UV and break-down much faster. It's not all about esthetic's.
