At least during the construction of the tail cone, the instructions says not to dimple and no mention of edge break for this area. I guess I need to double check those pages. Remember, this part does not get riveted but screwed, there will be a thin layer of proseal or other type seal used for water proofing and you want an straight skin so the aft canopy part can easily slid in-out for fitting.
