If it is a deep wide wound be wary of the underlay material you use before you gel coat over. I recently threaded "transom repair" and Finnegan brought up an interesting and important detail. The gel coat is a poly resin base and does not adhere to in place epoxies (epoxies do adhere to in place poly resins). From other posts minor hole repairs make this incidental. However, if you are repairing a wide area, best to take the material compatibility into consideration. I have existing repairs with epoxies (Splash Zone) and and am sticking with it for my hole repairs but have ordered some "System III, SB-112" which acts as a bonding primer/stick coat for poly over epoxy.
