Static tint film…. ????

Moin moin, does someone know what I’m talking about and maybe even one in it ? wiel I wanted to let my slices sound in my Civic (Eg3) back (or have tint film installed, for the rear three slices) then I was told, because the slices are not removable and since in the two side slices there would be a arch in it, would that cost me in their workshop 413 (!) Euro *scratch at the head* I almost fell out of all the clouds… well, now I’ve got a bit of a circumference listen, and I’ve come across electrostatic tint film. In other words, you cut it right, you pat it on it and it hangs. And when I’m just funny, I just do it again… sounds very good in my opinion. Too good actually… especially at a price of no idea, 15 euros or so for a role. So someone has experience with ? or, has there ever heard of anything???
