Automobiles have come a long way from their boxy, purely utilitarian origins to become status symbols that are well taken care of for showing off. That's why, even if your Chevrolet Avalanche 1500's fenders are specifically designed to absorb and blunt the force of impacts, no one wants them damaged and cracked-it doesn't look good at all! The thing is that impacts are not the only source of damage to the fenders, time and the elements also play a major role in determining the longevity of these parts. The following is a guide to some of the symptoms to look out for to make sure you deal with trouble before it begins.
Exposure to different weather and climate conditions and dirt on the road on the road are some of the culprits responsible for deterioration of your fenders. Beyond just looking bad, though, these physical changes actual warn of a far greater danger-a weakening of the surface and structure of your fenders. In fact, more often than not, the discoloration is a result of a thinning or erosion of the layers that compose your fenders. This thinning and erosion is dangerous because it means that the fenders are much weaker and less capable of handling impact damage. An option once you start noticing discoloration is to buff up the area with polish. Even a coat of automotive paint helps to bolster the fender. If rust starts to form, however, you have little choice but to replace the entire fender.
Apart from the surface of the fenders, the plastic attachment points are another point of vulnerability in the fenders. Damage to these points is difficult to detect if only one to three are actually broken. The reason there's a banging noise is because, when your vehicle is moving at speed, the wind passing along the sides cause strong vibrations that cause a "flapping" in those areas that have the attachment points broken off. A quick fix for this, short of a replacements is to carefully re-secure these attachment points with putty or any strong-yet impermanent-"filling" material.
