Can anybody confirm whether the black edge trim that goes on the fibreglass roof should go all the way around the roof, or does it start at hinge 1 and finish at hinge 3

leaving the middle section free of trim ??
In my kit of parts that I purchased from "Dormobile" was the edge trim, but it's too short to go all the way round. Does anybody have a pic or two to confirm my thoughts ??
Thanks in advance
