You can sand down/remove the crinkled up paint and then apply a coat of clear nail polish over the area. If you've got some time, you can get a nail polish to match almost any frame color because of the assortment of different shades. You don't have much to worry about on a Aluminum bike, but I always do it. If you ever have the same problem on a steel framed bike, you are definitely going to want to do this or apply a coat of touch up paint pretty fast after it happens.
