The windshield trim is a complete PITA. Gonna be worse if someone has already removed & reinstalled it. The parts car I got had about 32oz of silicone spooged all over. I tried to remove the trim as it waa actually in good shape. Ended up throwing it away.
For the sail trim, I used a flat paint stirrer (Home Depot, etc) to lay on the body work, then use a 5-in-1 tool to lever the metal off the plastic liner (starting at the back, working forward & up), then pull the liner off. Mine has the black plastic coating, and I got it off without marring the coat. Screwdriver is NOT good as load is too localized, and putty knife will flex too much, IMO. As mentioned be very careful with the end tips, very easy to loose them! Careful with the center junction cap also.
