NOTE: The following illustration(s) are not all-inclusive of trim levels available. The actual trim level of the vehicle will
determine the viability of carrying out a plastic repair.
Several considerations will determine viability of plastic repair procedure(s):
• Is the damage cosmetic or structural?
• Can the repair be carried out on the vehicle?
• Is the part readily available?
• Is component repair the most cost effective method?
• Can the component be economically restored to original strength and appearance?
• Will the repair provide for the fastest, highest quality repair?
Several types of plastic are in use for automotive application. However, all plastics will fall into 2 primary categories:
thermoplastic or thermosetting plastic.
Thermosetting Plastic
Generally, thermosetting plastics are made with 2-part thermosetting resins. When mixed together, heat is generated,
producing a cure that is irreversible. Because of this, thermosetting plastics will require the use of a 2-part adhesive
for repair.
Sheet-Molded Compound
Sheet-Molded Composite (SMC) is a type of thermosetting plastic that uses glass fibers or nylon fibers in combination
with thermosetting polyester resins. When fully cured, SMC is strong and rigid.
SMC is similar, but not identical, to fiberglass. Ford Motor Company uses SMC in components such as fenders, hoods
and liftgates.
