Mercedes Benz 300D Fender

Symptoms of a Defective Mercedes Benz 300D Fender

The fender on your Mercedes Benz 300D's primary function is to keep dirt, debris, and other particles from the wheel and the braking system. Over time, dirt buildup will cause corrosion and rust holes, which will compromise the part's durability. If you suspect that the stock fenders are already wearing and tearing, then you had better perform some troubleshooting. Listed below are a few common problems encountered with defective Mercedes Benz 300D fenders and the reasons behind them.

Rusting fenders

A common defect encountered with metal parts is corrosion. Over time, the fenders on your auto may exhibit signs of rusting. This can be a result of aging parts or by improper cleaning and maintenance. In other cases, you may cause premature rusting by constantly driving through puddles of water. Failing to wipe off wet parts can increase the rate of wear and tear and can greatly decrease the fenders' durability. To check for rusting, simply inspect the fenders for rust holes. Be sure to check the inside parts as well because they can be hidden from view. It's a good thing addressing rust is easy. Simply remove the loose rust with sandpaper and apply some rust dissolvers.

Fender benders

Most cars are designed with an easy-to-remove fender because fender bender is a common case. If you recently experienced a minor collision and the fenders have been damaged, then your best option is to find a replacement. Even if you have not been in a collision, there are several instances where the fenders can get damaged. There are cases when fenders are bent because of improper parking, or other drivers may have simply miscalculated and accidentally hit your auto. Attempting to repair them back into shape may cause several other defects like rim or tire damages, so your best option is still to find a replacement for the stock part.

Rim damage

Rim damage is often a result of unaddressed fender benders. They are easily detected when driving because of an unusual vibration in the steering column. If this happens, check if the fenders come in contact with the rims. They should be replaced immediately to prevent premature tire wear.

    Your Mercedes Benz 300D's fenders are built tough and durable in order to withstand constant exposure to dirt and grime. You see, these metal parts prevent dirt and unwanted particles from entering the wheels and compromising the car's brake system. But since these parts are the ones taking in the damage, you will likely see them full of rust spots and corrosion. When left unattended, these rusting parts will also damage your car's appeal. If you want to keep these problems to a minimum, then follow these quick, easy, and trouble-free ways in maintaining a fully functional Mercedes Benz 300D fenders.


    Repair minor fender benders with a plunger or hammer.


    A minor bump on your fenders can easily be addressed with a plunger or hammer. Just moisten the edge of the rubber and place the plunger over the dent. Create suction and pull the fender part toward you. This technique should work after a few tries. If not, you may try using a hammer. Make sure that a rag is wrapped around the hammer to prevent damage to the paint job. This can be a bit tricky because you might miscalculate and hit a perfectly fine spot, causing more bumps and dents.


    Fill small dings with glazing putty.


    If there are parts of your fenders where the paint has been chipped, you can fill them in with glazing putty. Painting the area is easily done with a putty knife. It should not be that hard to find one in your local home improvement or department store. If the dings are quite large, you may resort to body fillers, which are available in an auto supply store.


    Remove signs of rusting and corrosion.


    Dents and dings left unaddressed will result to more fender damages since the metal parts are exposed. So, to keep this from happening, prepare a wire brush or steel wool once you find hints of corrosion. You may also apply some rust dissolvers to speed up the cleaning process. As an alternative, you may apply a solution of lime juice and salt if you have a limited budget for the dissolvers.
