I am new to this whole boating thing. I have owned PWC, but nothing with an outboard motor, or aluminum rivets. lol. I have a 14 ft gamefisher, and It seems to have a slight l leak. Nothing major, but enough to bother me. I believe its under the middle seat. My question is, I have heard things about J B Weld *Marine*, and this Gluvit stuff. With the Gluvit, would I seal it on the outside bottom? Or inside bottom? The same with J B Weld. Inside or outside? Im not sure if I am making sense, but I would like to get this small leak sealed just for peace of mind. Id like something easy, and cheap. Any suggestions?
