[Ron Mummert]

I was forced to remove all my perfectly good tinting to pass a state inspection. I took the car to a professional tinting place. I had the same apprehensions about the de-fogger wire as you do.
The "professional" kid who removed it said, "Don't sweat what I'm about to do". He then picked a corner free, & just ripped that thing off in a split second. All wires stayed where they were.
Get some sleep.

Ron.
