I looked into this just receintly. I found that the options are paint, or an epoxy finish coat that can be colored. Look at epoxy suppliers for the product.

West Sytems claims that you can.

I just did a patch job on my boat using West Systems mixed in with filler and gel coat on the top of it. We will see how it holds up.

I've called West Systems about this, they said well, it does sort of work, but might not the the best way to do it.

I sell gel coat and my answer is never use gel coat over epoxy. I've tried to get a good bond before and while you can get it to stick, it was never a strong bond. I was never able to get a good enough bond for me to be comfortable with doing it on my own projects, or for any body else.

By the way, all our chemists also say it's not a good idea.
