Fiberglass crack

[HR4ME]

Hello. Here's a pic of a small crack I just found in my fiberglass sidewall. How bad is it? What should I do about it? Thanks!

Stress fracture, from what it's hard to tell. If you can't fix it yourself, have a body man clean it up. I would take some JB weld, apply a thin coat, a little sanding, the right color paint, then wet/dry 1000 and 1500 sand paper to smooth it out and then clear coat and some buffing. If you got the time that is. Good Luck

Thanks. You can see in the pic that it seems to start under the window. Do I need to pull the window out to do the fix?

And do I need to worry about it running before I can get the fix done? Do I need to rush it? Thanks.

To really do it right, you need to get behind the crack to reinforce it. But you know your not going to be able to do that. Another way would be to open the crack up and fill. Again i would try a thin coat over it and hope it stays secured. Good Luck.

I would pull the window just to see if there's some water damage. It would make it easier to fix the crack as well.

you can also drilll a small hole at the end of the crack to help prevent it from expanding more. It will relieve some of the stress. Then do your repairs. Google fiberglass boat repair and get some hints on how to do it.
