A unique transport stabilizing combination for stabilizing items during conditions of movement comprises a viscoelastomeric thermoset overlay disposed upon a vehicular support member. The viscoelastomeric thermoset overlay component of the transport stabilizing combination is desirably viscoelastomeric, adhesive, cohesive, releasable, antipathogenic, cleansable and/or reusable. The vehicular support member is desirably an extension of a vehicle, and the transport stabilizing combination can stabilize a portable item against movement and damage during conditions of movement, such as rocking or during transport.
