    Caulking

    I have a 14' Lund aluminum fishing boat. It is getting a few minor leaks and I noticed the caulking along the seams has seen better days. I was going to pull the old caulking off and reseal it with silicone. Will the silicone be adequate or is there something better to use? Thanks,
