Ok, here it is. I had a small 30" gun (here) that i bought a new piece of wood for and thus extended it to a 50" gun. the handle is plastic and the end of the piece of wood fits inside the plastic handle. my question is this: should i seal the wood inside the plastic handle with silicon or should i just leave it be? because the old piece of wood that was in there had an amazingly tight fit and it still had some water leakage in the pocket where it fits into the handle.
