What role does body filler play in the repair process?

Body filler is primarily used to smooth out imperfections and provide a paint-ready surface. In the repair process, after damage such as dents, scratches, or other surface irregularities are identified, body filler is applied to these areas to restore a smooth finish. This compound is formulated to be easily moldable when applied and hardens to create a solid surface that can be sanded down to exact contours. Once shaped, it creates an ideal base for further finishing processes, such as primer and paint application.

While body filler can help to create a level surface and improve the overall aesthetic of the repair, it's important to note that it does not provide structural support or a protective coating by itself. So, its primary function in the repair process is to ensure that the repaired area is uniform and ready for the subsequent application of paint, ensuring a seamless and visually appealing finish.
