I just bought my first boat. Its a 1969 15' Boston Whaler. The hull has a few splits and cracks in the fiberglass inside that I am trying to fix but have no clue what to use on it. Im trying to find the cheapest, but most reliable way to fix it. I was thinking auto body filler unless you guys can recommend something better. I attached pictures to give you an idea of what I'm working with. Thanks in advanced for the help.
