Sometimes nevertheless, a fracture will appear and divide the bumper and this must be dealt with differently.

If your cracked bumper isn’t repaired or the repair is completed with filler that was normal, the bumper’s structural integrity is compromised. It is essential that the fender crack is treated and rejoined with a tough yet flexible resin. A particular technique is used to accomplish this which must be carried out every time.

Typically the crack doesn’t appear severe, it often has the appearance of a hairline fracture and it’s tempting to run a small filler over it and treat that as fixed. The effect of that is that the next time the bumper is put under any pressure at all, the crack will reappear and generally widen. The crack should be widened, efficiently worsening the damage, initially so that there is enough of an opening for the resin to fit in. There is a hole drilled at each end of the crack, half on and half off the very end. This permanently ceases the crack from jogging again.

Care must be taken if sanded, as the bumper resin can melt. After the resin has fully hardened the fender is structurally sound again and will be sanded, filled, primed, painted and lacquered as normal. Result – a perfect fender repair
