• and
• wherein the metal substrate portion is subjected to one or more surface treatments to ensure bonding of the overmold portion to the metal substrate portion.

A method of forming a structural member of a vehicle, comprising:

• forming a metal substrate portion;
• applying one or more surface treatments to an outer surface of the metal substrate portion;
• and
