Cracked Bumper? Repair It the Smart Way.
A cracked bumper is one of the most common car body repairs performed by intelligent (Small to Medium Area Repair Techniques) repair operatives. Bumpers are made to manage like being hit by a shopping trolley, low speed scraping collisions with other vehicles and car park barriers along with other minor impacts low impact collisions. Often this kind of injury results in dents, scuffs and scrapes that can be fixed easily and quickly by way of a mobile auto body repair technician with lacquer, primer, paint and a few auto body filler. Occasionally nevertheless, a crack will appear and split the fender and this has to be dealt with differently.
If there is a cracked fender not fixed or the repair is carried out with regular filler, the bumper’s structural integrity is endangered. It is vital the fender fracture rejoined and is treated having a hard yet flexible resin. A specific technique is used to execute this which must be carried out every time.
Normally the crack will not look intense, it often has the appearance of a hairline crack and it’s appealing to run a small filler as repaired, and treat that. The end result of it is the next time the bumper is put under any pressure at all, the crack often widen and will reappear. The crack must be widened, efficiently worsening the damage, initially so that there’s enough of a gap for the resin to fit in. The crack permanently ceases from jogging again. Next, a v-shaped groove must be made right down the crack’s middle, wide enough for the drill bit without going off the boundary of the crack, to make a hole.
A strip of net is subsequently placed on the interior of the fender all along the damage – this will hold the resin in place while it hardens and could be left there afterwards. A mix of resin and Alloy Wheel Repair Hornchurch hardener, especially formulated for fender repairs such as this, is then injected into every one of the holes which have been drilled. The purchase needed to forbid the resin going straight through is provided by the mesh backing. The aim here is to effectively “stitch” the repair together.
After using the resin, a body filler spreader (or ideally specialist contouring movie) can be used to smooth the repair on the top side of the bumper to minimise the sanding which will be demanded afterwards. Caution must be taken if sanded too vigorously as the fender resin can melt down. Following the resin has completely hardened the bumper is structurally sound again and will be sanded, filled, primed, painted and lacquered as regular. Result – a fender repair that is perfect
