Never pay before hand....
Heck, I just had a tint job done and they did it, scratched the CRAP out of it while installing it, when I brought it to their attention, the guy was like, it will go away.
Well, three days later, it never went away. Took it back, and he treated me like trash. Don't pay in advance, otherwise, no go on the getting a good tint job...
And what kind of tint are they using that you can open the windows the same day? I've never seen tint like that...You may check into that a little more.
