Under the top edge (line of bolts under the bonnet).
Also has almost as many uses as duct tape around the home / car!

Originally, this sealant ONLY was used between the inner & outer wing on the top edge. The inner wing top surface was not painted first - just left bare metal.
This was a bad move by Audi and is why the top of the inner wings rust under the outer wing.
After any repairs are done, paint the top surface of the inner wing before you fit the outer wing.
