sealing Bulkhead

The forward bulkhead in my WS Tsunami 125 is leaking from a bad seal. Any idea how to seal it. The boat is not that old. LL Bean said I could return it but that is a real pain. A guy at the EMS store said I could use gorrila glue.

i would use Lexcel, its clear and i think thats what the factory uses, you can find it at most true value hardware stores, i have put several bulkheads in, i used it and never had any problem with it. good luck
