Just now saw the replies. I have to agree about the only thing you can do is try a heat gun (carefully) and see what happens. Who knows what you have on your boat.?? It could be anything but odds are it is preshrunk and there isn't much you can do. If so, paddle it and see what you think. Then if you like it well enough you may want to reskin it over the winter.

I have one I hated the skin, finish, color, etc. Finally reskinned it and now I am happy with it.
