I've used it and it worked great. I'm sorry but I don't remember the exact color, i think it was almond. If you dig around with Google, you'll find a reference to the Grady color. That's what I did.
Spectrum Gelcoat is real easy to use, match hull color and purchase from any dealer or directly from the Spectrum website - there customer service is great as well.
That's what I've been using. I have found that it takes 2 applications to build up enough to be flush (I'll bet there's a way around this). I've been using a little bit of surfacing agent in the mix too, and then razor scrape, wet sand, rub, polish. I have a can of the factory gel from my year and it matches pretty well.
My smooth surfaces are coming out great. The textured ones only so-so...
