1. Fender: Fender is the US English term for part of an automobile (vehicle body of car) that frames the wheel well (the fender underside). Its primary purpose is to shield wheels and protect both passengers’ compartment and pedestrians from projection of water, mud and stones. Fender is one of the styling components…

1. Wheel Arch: Wheel Arch is the semi-circular part of the fender positioned above the wheel of the vehicle.  The design of Wheel arch of a fender should be such that it must shield wheels and protect both passengers’ compartment and pedestrians from projection of water, mud and stones. For the vehicle to has…

UNDERBODY COATING AND ITS PURPOSES: Modern automotive coating methods consist of five main steps. They include the following: Pretreatment: removes and cleans excess metal and forms an appropriate surface structure enabling bonding of a corrosion protection layer. The next step is electrodeposition (ED) of the anti-corrosion…
