My tent turned out perfect. From an engineers prospective, there is no way to go on manufacturing specs. when doing tent. The tent comes in rolls and must be measured and cut to fit each window. I can't quite see how they can pre-cut (and this is what it sounds like) tint to fit a window. Then the tent has to be measured and cut for the outside of the window thus, making the dimentions a tad larger than the inside due to a slightly larger surface area. When this cut tent is then place on the inside of the window where it should be, the tint sheet should be large enough to push down into the door/window slot and also be largre enough to slide around into place. Soap is used to make this happen and then pushed out with a straight blade to get rid of the bubbles. There might be a few bubbles but if it is done correctly, will disappear as the tent dries onto the window itself. I would make them redo the tent. (I don't mean to sound negative) but this sounds like a group of people that may be buying tent from the local store and ran short with the material.
Just a thought - Let us know how it goes and I'm sure with enough pressure your tent will be fixed. If satisfaction can't be found, I would tell them to remove the tint, return your money and go some where else.
Regards and good luck,
