I normally do a re-finish
Give it a good rough up with 60-80 grit, then fill all the chips with a high build easy sand putty of some sort.
Then just sand them back to flatten off the finish, fill any dings and scratches you find at the same time.
Then simply paint over it, do a layer of primer first if the colour is majorly different, but otherwise just make sure you have sufficiently sanded it (no shiny bits) and paint straight over.
Good as new
