Hi all, not sure if this question is proper here, but here it goes anyways. The permanent plastic gas tank on my boat has a small crack on the top of it. Part of the tank extends out from under the boat and I wonder if a dab of silicone would be safe to seal the hole. Not sure if the crack is all the way through it, but don't want to take chance of water leaking in.
