Hi donee - I used a kind of thick silicone type stuff. I don't remember exactly what type it was, which isn't very useful. It pulled equally off the painted surface of the wheel arch lip as well as the skirt plastic itself.

Regardless, velcro wasn't practical. Even if the adhesive had stuck, it was too hard to install & uninstall the skirt (the velcro would grab before you had it in position, etc.)
