All vertical panels, fenders, doors, quarter and rocker panels are made from rigid thermoplastic. Front and rear fascias (bumper covers) are constructed of thermoplastic olefin (TPO). The hood, roof, and deck are steel.

Different materials require different procedures for repair and refinishing. Before starting any repair, identify the type of material involved and follow the correct procedure.

For ease of understanding the repair processes, they will be addressed according to the level of damage. The following chart outlines the level of damage and repair process for exterior plastic panels.
