If I may suggest although it is too late maybe, your seal does not cover enough area. If you have the top seal where yours is water can sit in the pocket you have created and was there in the original gasket when it was installed. Water and dist and grime will accumulate and over time create a rust trap which will be fed every time it gets wet.
The bottom flat area also has to be kept dry to prevent water sitting on the shelf as it does not drain.
My original gasket had the better arrangement but it just moved away from the ideal location and then allowed a little leak.
You can see in this picture how my original seal was very close to the outside face and then sloped down toward the edges allowing the water to move to the outside area where it can run down and under the lower panel.
The vertical seals are also on the higher plane and not on the bottom face like yours, again keeping the water toward the edges.
I am intending my bottom seal to be as close to the wing emblem as I can to keep water off that flat shelf area as much as I can.
Mine is back on and the RTV is fully cured, so it's not coming off now unless I see more leaking. I left the stock gasket on, but I liberally applied a thick coat of right beside it to ensure a waterproof seal. I didn't find any leaking the past two days after driving around in the rain, so I may be out of the woods. Thanks for the advice though.
