Fibre glass roof repair

[ashtons99]

i have a very slight leak on my glass fibre roofed garage extension. I have traced it I think to where the matting laps over the raised edge trim, it's either there or it's percolating through a small area where there seems less gel coat/resin over the matting.
What is the best way to cure this, I'm hoping I will be able to perhaps prepare the surface somehow and lay some more matting and resin over it.

Is there more to it than this, what is the actual process. Any advice would be appreciated

One of the benefits of fiberglass is that its easy to repair. Clean the area thoroughly, scour away any dirt then use acetone. Then you can add some more matting and resin
