If you're bothered about exact colour matching , 1200 grit and polish the area round the ding before you start sanding inside the ding.

You may find that you need to build it up with a couple of coats of gelcoat then add wax in styrene to the last coat to make it go off properly if it's a large chip.

Farecla Profile 300 is very very good for the polishing stage-you only need the one polish rather than going up in grades.
ok thanks for the advice! will give it a crack and hope it works out a bit better this time.
