Well, if you cant feel the scratches then you can buff them out and I would do it yourself if you know how....as for the dings get some Kombi Putty, spraypaint, and clear here:
www.paintworldinc.com or by calling 1-800-548-4321..... all materials together might run you about $30 - $40.....and it will take you about 4 hours to do the job but most of the time is spent waiting for the coats to dry. Actual work is probably 1 hour. Just call that number and have your color code handy and they will take good care of you.
