Our installers are very talented and experienced in managing tension. Here are some before/after photos.
Below, you can see how involved this Supra hood is. Getting the stretch right, before squeegeeing is essential.
Below, you can see this Cadillac CT5 hood is much flatter and requires much less tension management. The principal remains the same but the stretch is different.
The Tesla Model Y rear hatch shown below shows a seamless install, This is done in one piece of film, instead of a kit install which requires a seam across the body line. It is a good example of managing tension properly.
