Crack in my fiberglass
« on: June 13, 2018, 07:09:32 PM »
I just found this problem today. Thre is a two inch crack in my finerglass skin, diagonally, about 2" long, right at the corner of one slide.

My first thought is to drill a small, shallow hole at the end of the crack, then dremmel the crack out a bit for a bigger line and cleaning, then appoxy it up with some JD Weld or some other appoxy that aheres to fiberglass.

Please, if anyone knows a better method of repair, or better material, let me know.  As usual, I always appreciate everyone's input. Bob

In addition to your suggested fix, if you can get behind the crack, apply some fiberglass mat.

you said drill a shallow hole.  I don't know if I understand what you mean, but I think you need to drill a THROUGH hole to break the stress riser.

Brad, do you mean drill a through hole at each end of the crack to stop it from spreading. They do that with cast iron.

exactly that. 
Done for pretty much any material that is brittle enough to crack.

Thanks Brad, I will drill the hole all the way through through the fiberglass at the end of the crack.  Your help is appreciated.
