The SMC (sheet molded compound) hood consists of several parts including fenders, hood, and inner
reinforcements which are bonded together with a structural adhesive and rivets. If the hood is damaged,
determine which parts are affected.
Damage at any joint between two parts is not repairable. For example, if fender and reinforcements
bonded inside the fender are damaged, replace the entire hood assembly.
If a joint between two parts has separated and there is no damage at the joint, the parts can be
rebonded. Or, if a part is damaged and adjoining parts are not, the damaged part can be separated from
the hood and new or used parts can be bonded in place. A section of a part can be replaced as long as
the section does not include a joint between two parts. Fenders and headlight reinforcements are available
as replacement parts or for use in section replacements. If the damage is such that parts cannot be
replaced or a section replacement cannot be done, replace the entire hood assembly.
