If there is a cracked fender not fixed or the repair is performed with ordinary filler, the bumper’s structural integrity is compromised. It is vital that the fender crack is treated and rejoined with a tough yet flexible resin. A specific technique is used to accomplish this which needs to be carried out every time.
Typically the crack does not appear intense, it frequently gets the appearance of a hairline fracture also it is appealing to run a little filler over it and treat that as repaired. The end result of it is that the next time the bumper is put under any pressure at all, the crack will reappear and often widen. The crack has to be widened, efficiently worsening the damage, initially so that there is enough of an opening for the resin. There is a hole drilled at each end of the crack, half on and half off the very end. The crack is forever stopped by this from jogging again. A v-shaped groove has to be made right down the crack’s middle, wide enough to create a hole without going off the edge of the crack.

A mix of resin and hardener, especially formulated for bumper repairs such as this, is subsequently injected into each one of the holes which have been drilled. The purchase needed to avoid the resin going right through is provided by the mesh backing. The aim here would be to effectively “stitch” the repair together.
