The Mercedes Benz E430 bumper trim, whether it is made of plastic, chrome, aluminum, rubber, or steel, is made to reduce the amount of damage to the bumper's finish. And while performing this duty, it gets damaged as it is exposed to all sorts of debris and changes in temperature and environment. Here are some common problems you may encounter with the bumper trims and the reasons behind each of them:
Because of its main purpose, the bumper trim gets most of the abuse that would otherwise have been directed to the bumper's finish. No matter which material your bumper trim is made of, scratches are simply inevitable wherever you drive or park. One careless move can cause a whole bunch of new scratches, especially on bumper trims made of softer materials such as rubber, plastic, and vinyl. A scratch deep enough in any of these surfaces will create the need to replace them altogether.
Plastic or rubber bumper trims, especially when black, can get discolored over time. This is because of the damaging UV rays of the sun, road dust, and changes in the environment. The rubber bumper trims are even more sensitive to UV rays and lose their color when not applied with a protective coating. The chrome bumper trims, on the other hand, will start to tarnish and turn dull over time when they are not polished and cleaned regularly.
Aluminum bumper trims are highly resistant to rust, but are still not rust-proof. In the case of chrome and steel bumper trims, a regular cleaning and polishing is necessary. Otherwise, rust and corrosion will surely develop. The dirt and grime that may build up in the crevices may contain salt from the road, and if left unattended, they will start eating away the metal and will also damage the plating.
Some car owners are sometimes baffled when they notice that one or some, or even all, of their bumper trims are gone. This is the result of weakened adhesives. Since the bumper trims are exposed to heat and sunlight and, sometimes, even rainwater, the adhesives weaken and come to the point where they will no longer be able to hold the weight of the trims. Hence, they fall off.
