Fiat Bravo

Need help on tinting a bravo rear window. this is the most curved window ive tried and ive wasted alot of tint trying to do it. im using dartztints. is it possible to shrink these without creases. lol

It is the first back glass that I did in one piece
It is very simple, ....

take it to a pro...or waste more film

ive never had any problems with other cars. maybe its coz this is my own. did u use a wet shrink or dry shrink??
