A cracked bumper is among the most frequent car body repairs carried out by intelligent (Small) repair operatives. Fenders are designed to handle low impact collisions such as being hit by a shopping trolley, low speed scraping scraping collisions with other vehicles and car park barriers as well as other small impacts. Often this sort of injury leads to dents, scuffs and scrapes which can be fixed quickly by way of a mobile car body repair technician with lacquer, primer, paint and a few auto body filler. Sometimes however, a crack will appear and carve the bumper and this needs to be dealt with otherwise.
In case a cracked fender is not repaired or the repair is performed with ordinary filler, the bumper’s structural integrity is compromised. It is essential that the bumper crack rejoined and is treated having a hard yet flexible resin. A particular technique is used to accomplish this which ought to be carried out every time.
Usually the crack does not appear acute, it frequently has the appearance of a hairline crack and it is tempting to run a little filler and treat that as fixed. The consequence of that is the next time the bumper is put under any pressure whatsoever, the crack commonly widen and will reappear. The crack must be widened, efficiently worsening the damage so that there is enough of an opening for the resin to fit in. A hole is drilled at each end of the crack, half on and half off the very end. The crack is permanently stopped by this from jogging again. A v-shaped groove should be made down the centre of the crack, wide enough for the drill bit without going off the edge of the crack, to create a hole.
A series of holes, one on each side of the crack every inch or so along the entire period of the fracture have to be drilled. A strip of net is then placed on the inside of the bumper all along the damage – this will hold the resin in place while it hardens and may be left there afterwards. A mix of hardener and resin, specifically invented for fender repairs like this, is subsequently injected into each one of the holes which have been drilled. The net backing provides the Alloy Wheel Repair Essex purchase needed to avoid the resin going right through. The aim here will be to efficiently “stitch” the repair together.
After employing the resin, a body filler spreader (or ideally specialist contouring movie) is used to smooth the repair on the top side of the bumper to minimise the sanding that will be needed later. Caution should be taken if sanded vigorously as the bumper resin can melt. Following the resin has completely hardened the bumper is structurally sound again and could be sanded, filled, primed, painted and lacquered as regular. Result – a fender repair that is perfect
