hi,

I had the same problem a few times, due to a to cold environment and resin not mixed well enough Blush, my bad.
What I did was start again; Because I didn't know what caused the problems and wanted to find out what the problem was.
It was a small part 25x25cm. 

- I don't know how big your part is but you could sand it of, back to the fiber (don't go to deep!) and put some resin on it (few layers with sanding inbetween the layers)
- Or if you have Gelcoat chipping of you maybe remove it with a hammer and chisel, but you'l have to be very carful not to go into the fiber.

just like you can read those are timeconsuming steps... and its sometimes easier to start again.

Maybe a picture of the part could help to give more/other advice.
