    Hi friends,
    Thinking of buying a boat and it has a couple of marks and scrapes. If I do buy it, I plan to spend a few months doing it up but I am new when it comes to working with fibreglass.
    Would you have a look at the attached image, this gash is about 10 inches across. What do you think, is this capable of a DIY repair? If not, what cost to have it professionally done?

    Many thanks

    I have pics of the boat but have cropped this one here to maintain the sellers privacy. Just watched a few fibre glass repair videos on youtube that answer my question. It seems it is a simple material to repair particularly for small damage such as this.

    The faded blue gelcoat has completely de-laminated from the underlying fibre glass layup.

    You will want to know "why?"

    Yes, it can be repaired, but use epoxy resin which sticks better (chemical and mechanical bond) to your repair than polyester resin.

    Note that you will not be able to match the gelcoat blue colour, which appears to be quite faded in your picture.

    As above, curious to know what kind of boat.

    Many thanks, yea the gelcot is lifting. What might typically cause that? BTW the boat is listed as a seahog 16'. Does that ring any bells?

    It's hard to tell if its osmosis or a stress crack, osmosis happens when the fiberglass absorbs water causing the gelcoat to lift off if it is osmosis you may have to strip off a lot more of the gelcoat to find a place where there is a good bond before you can fix it. If it is a stress crack just grind it out and build it back up with epoxy resin mixed with filler and then smooth out. I use west system resin mixed with 404 fillers, you may also need to put some fiberglass cloth on the back of the repair to give it some strength.
