Mostly fiberglass cracks on boats are caused by stress. Stress cracks are usually attributed to the gel coat that lies below the fiberglass.

.. IN RESPONSE TO :.... cyanoacrylate (super glue) wouldn't work as well as fiberglass resin and cloth. Fiberglass is not a real "solid", it is a thermoset plastic. The resin matrix and glass mix will "move" during heating and cooling cycles. cyanoacrylate (super glue) will work for a short period of time, but cyanoacrylate (super glue) does not stand up to vibration and heat/ cooling cycles as well as you would think. that is why the "glued" on mirrors fall off. Best to drill a small hole at each end of the crack and fill with the proper resin / glass mix.

I am restoring a Corvette which has some minor stress cracks. The usual method is to grind down the crack and epoxy fill. And then paint. I am wondering why cyanoacrylate (super glue) wouldn't work as well. It permeates tight spaces and in my woodworking experience doesn't bleed through a lacquer finish. I expect to coat the car with a catalyzed sealer and then polyurethane.
