I would respray them. The fiberglass grill on my '97 Aerbus had a lot of chips on it so I decided to respray it a year ago. First I cleaned and sanded it. Then I applied a few coats of adhesion promoter (sanding in between coats), then applied a few coats of primer, applied a few coats of factory color spray paint (sanding in between coats), and then finished it with a few coats of clear coat. I have very happy with the results and it has held up very nicely. Looks like new. I did this over the course of 2 warm days as I wanted to make sure to give it a lot of time in-between coats to dry and cure. Good luck!
