Hopefully you last longer than I did, I wanted more after about 2 weeks lol.
In the blistering U.K. heat both door card leather bits were sagging and coming away. (Probs more the fact they're 16 years old glue)
Took both doorcards off and pulled the leather away enough to get some carpet adhesive on it.
Waited till tacky then used a plastic squeegee to pull tight.
Only got an after shot but happy as it was annoying the hell out of me.

Open windows at higher cruise speed can also cause this to happen, because it allows air to get through in between ...
I'm fixing my left door card, every 2 months... at last i notice that, my right door card is trying to fall apart too..
I'm using some type of high temp spray glue
