PLASTIC BODY PANEL REPAIR There are many different types of plastics used in today’s automotive environment. We group plastics in three dif- Rigid Plastics: Examples of rigid plastic use: Fascias, Hoods, Doors, and other Body Panels, which include SMC, ABS, and Poly- Semi-Rigid Plastics: Examples of semi-rigid plastic use: Interior Panels, Under Hood Panels, and other Body Trim Panels. Flexible Plastics: Examples of flexible plastic use: Fascias, Body Moldings, and upper and lower Fascia Covers. Repair Procedure: The repair procedure for all three categories of plastics is basically the same. The one difference is the material 23 - 4 BODY LX |
