Spectrum Color
http://www.spectrumcolor.com, has color matched gel coat repair kits for many manufacturers. Depending on the amount of repair work necessary, they have a small 2oz gel coat paste repair kit for about $27. I did this on my SeaRay 280 Sundancer a few years ago and the color match was terrific. Relatively easy to do (once you get past taking sand paper to your gel coat )

I have no connection to Spectrum, just have used the product and it performed great and still looks great.
