Honda does not have a sectioning procedure for the B-pillar reinforcement.

Per our contacts at Honda: “Do not section reinforcements unless a specific procedure is provided in the body repair manual. Replace body structural parts such as stiffeners, reinforcements, and other multi-layered steel parts as assemblies that match the replacement parts configuration, or body repair manual repair procedure.”
