When I bought touchup paint at a Honda dealer, they gave me a vial with a brush. At the Acura dealer they gave me a paint pen. That makes me think the pen is better. I haven't actually used the paint pen, but with the brush it's a pain to cover up little nicks without applying too much paint. A toothpick supposedly works better, but I didn't have much luck. Having a detailer touch it up and then sand it would be the best I think, but probably expensive.
