Sorry if this have been posted elsewhere, I did a search and can't find anything.

I'm in the middle of getting the pre-cut tint that I bought online installed.
However I'm having the hardest time getting the big pieces (driver side, front and rear passenger excluding the mini windows) installed correctly.

For some reason there are "fingers" that won't stay down at the bottom and side of those windows.
The seller told me that the software that they are using to cut the tint didn't indicate compound curve on them.
I know most back window have this problem due to their compounded curve (thus requires shrinking) but never on the side windows.

Does anybody here (that did the DIY) have similar problem?
This is the 3rd car that I tinted myself but I never got this kind of problem before.

Any input?

Thanks
