Drilling a hole through glass is really not a big deal.. Even if you were afraid to attempt it, a glass shop could do it for a small fee.. seems like a much more permanent, and better looking fix...IMO.. The 128 rally has opening rear quarter's, but it goes through the glass so you don't have to worry about adhesive sticking to a very non porous surface... It's fine for a rearview mirror, but a side window, held under tension against a seal? Seems like a bad idea.. Plus you have to realize, that over the years as consumer chemicals like paint, strippers and adhesives have become less toxic, they have become Much less effective than they were 45 years ago....
