Otto Says: I have heard rumors of people using JB Weld epoxy for this kind of repair, but I have never seen it done.3. thisiscrazy70605 Says: try some jb weld on it. sand it down good and make sure it,s dry and put some jb weld in the crack and over it, let it set up for about 2 or 3 hours before riding it.
