Prepping everything for the panel install. Sail panel.
If you look closely you can see the small faux spot weld dimples along the forward (drip rail) edge of the sail panel. The small reinforcement piece is welded in the corner of the quarter window. The faux spot weld dimples are in place along the wheel lip (foregound).
Everything is sealed with primer and scuffed where trunk spatter will apply.
The green tape is a small dam on the metal bracket to assist in catching the fusor foam which is later sprayed onto that ledge to dampen vibration to the sail panel. A lump of foam sandwiches between the inner and outer panel along that ledge.
