After cleaning the windshield with both aerosol window cleaner and then alcohol, the double sided tape I used since they didn't send enough 3M came loose on the highway. After redoing it with 3M VHB (very heavy bond) tape coupled with 3M adhesion promoter, the wire hider is almost a structural part of my windshield now. A bit pricy, but worth it since nobody else sells anything like it that I found.
