Hi. It's really hard to give accurate quote without seeing damage first hand. If you're local, you can bring boat by the shop and we can get you squared away. Keep in mind, spot repairs like this are more than just painting the chipped area. For beautiful results... you'd be looking at most if not all of capped area repainted.  Possible glass work/filling of chipped spots. Good news is, white is the cheapest color.
send me a pm if you'd like to discuss it further.
