I can tell you what didn't work so well for me.
I think it had more to do with how I held down the pad while drying.
I used 3M777 spray, which I have used for all sorts of applications successfully.
In the end the front has pulled slightly away from the metal leaving a 1/4 inch gap. I also damaged the thin chrome strip at the bottom of the dash which didn't help. So be very careful removing. As I recall it has some small nuts on the back side at the ends. Holding the pad in place while drying is very important. I think that's where I messed up. I wish I could give the right advice on that. Maybe someone else can chime in on a good way to hold the pad in place.
Good luck!
