I am wondering what type of Resin was used on Fiber Glass gas tanks ? I have a repair that needs to be done to a plastic fuel cell. It is a cell I had in my boat for the '07 Parker 300, it slipped and touched the alt pulley. I am thinking of using Sea Goin Poxy Putty and then sealing it with resin. It will be going back into the steel can after repair. I have heard of the plasic welding deal but I have not had any luck with it. Does anyone have any other Ideas ?
