After research I decided my original rear wing was causing nothing but drag, I highly doubt it helps to keep flow attached.
In the picture you can see where the wind resistance has removed all the clearcoat off the front part of the wing and has even Sanded Down part of the center section! Thats alot of wind drag resistance over the years to cause the wing to literally get sanded down in some areas.
Ill take a picture of my trunk and what I did to seal up the holes later. Ford Taurus actually came with trunks without rear wings too.
