fixing crack in fiberglass

azn370z · 10-16-2011, 03:08 PM

So anyone know how to fix a crack in fiberglass? I want to seal it before water gets in it and freezes. Is there a glue I can use?

That's going to require body work with more fiberglass and resin Then sand down, premier, and paint.

Doable but it is a multi step process... I'd probably have a pro do it.

Epoxy maybe?

It's a half inch crack. How about a glue?

For a very quick and dirty fix, I agree - 2-part epoxy. You'll might still be able to see the damage though, and it may recrack if it's near 32 degrees and part gets a decent tap. For proper, fix refer to other comments above. Depends on what you need and how much hassle you want.

What part broke, BTW?

It's a small line near the edge. I just want to seal it so water doesn't get in it and freeze. I'm not trying to hide the crack. Looking for something simple like a glue.

Epoxy = glue

azn370z · 10-16-2011, 06:31 PM

Ok... Perhaps a specific brand? Maybe gorilla?

I don't think brand matters. How about AquaMend Epoxy stick? Good for wood, fiberglass, metal....If good for marine applications, it should fine for areas exposed to moisture on your car.

I was going to say silicone if you were just worried about water getting in. It is pliable so that if it bends it won't break (but it won't help with the appearance at all). You can get it in all different kinds of colors.
