Fixing Common Problems with Mercedes Benz E320 Bumpers
Your Mercedes Benz E320 bumpers do a great job of protecting several vital components of your vehicle from minor accidents. However, this also means that the bumper itself is quite prone to all sorts of damage. Cracks and dents on the bumper not only look unappealing, they also reduce the overall functionality of the part.
Paint flaking off
Factory-painted bumpers usually last for the life of your car without any flaking problems. However, if your bumper has been subjected to shoddy repainting before, then cracked and peeling paint is to be expected. Properly repainting your bumper can be a painstaking task, but it also saves you from having to perform the same process over and over again. When painting your bumper, make sure that the surface is evenly sanded, cleaned, and primed, so that the paint will have no problems with adhesion.
Loose or hanging bumper cover
A slack bumper cover or a bumper cover that hangs off of one side is usually caused by worn-out or loose screws and retaining clips. Check if your plastic clips or push-pins are brittle or worn-out and replace them if necessary. If they get easily worn out, then your clips or pins are probably too weak to hold your bumper. Try replacing them with stronger clips or pins with a larger diameter head instead.
Small dents and deformations on your plastic bumper can be easily fixed using a heat gun or a hairdryer. Heat the dented area using your hairdryer or heat gun and pop it out with a wooden block. Be sure to have a cool, wet cloth in hand to allow the bumper to cool down quickly and hold its shape. Keep in mind that this process mostly works for plastic bumpers; dents on fiberglass and metal bumpers are much more difficult to fix.
Cracks and scratches
Minor cracks and scratches are a bumper's most common enemies. Luckily, many auto parts stores offer flexible epoxy glues or fillers that are made especially for the purpose of repairing bumper cracks. These fillers are pretty easy to use, but you might have to sand and repaint your bumper afterwards for a more polished look.
