How to repair a dented plastic panel or bumper

Hi all.

Recently, Ive been receiving more involved and complicated jobs (for a smart repairer, that is), an example was swapping over a car door on an '08 Corsa, and previously, painting & replacing a plastic sill on a '58 Altea Freetrack.

But one I did this weekend, which I'm particularly happy with, and have caught on camera, is one which you could do, if this unfortunately happened to you.

The car in question is a BMW X3 3.0TD, 18 months old, and the first pic shows the damage inflicted in a car park (which the owner returned to find)....

How I tackled this, was to remove the front wheel, and partially dismantle the wheelarch liner, which allowed me to get my hand onto the damaged part of the bumper. At the same time, in my other hand - I held a heat gun, and gradually warmed the affected area.

As the plastic began to heat up (which I could feel with my hand), it also began to soften, and I slowly worked it out until I achieved what you can see in the second pic after the plastic cooled & hardened up....

Its not absolutely perfect (the plastic was very stressed where it had met the inside edge of the wing), but the owner was well-chuffed (as was I).

Paint was then dealt with - job done!

The best advice I can offer, is to avoid applying too much heat (paint & plastic damage will occur), and to keep the pressure on the plastic whilst it cools, to ensure it solidifies into the desired shape.

Hope it helps anyone out there with plastic wing or bumper damage.

This job should never be complete - the day I think I've done it all, is the day I resign.
