I sprayed mine.... I would think that on the exterior application, the brush strokes would really show. Tape up really well before you spray. I went to the local newspaper; they sell the end rolls of the newsprint paper they use... there is quite a bit still left on the roll, great for little projects like these.
As far as colors, mine is now black/gold to match the awning. the original stripe on mine was woodgrain on a black background (limited package). THe woodgrain had faded to a yellow, so I just matched the gold on the awning. The later limiteds had burgundy stripes. all the other models were blue.
