FormulaOne Auto Tint classic™ series
This is an excellent film. It is a single layer construction, deep-dyed film. It is signal-friendly, meaning that it will not interfere with cell-phone, GPS and tire-pressure monitoring signals. It is the only dyed film on the market that offers a lifetime warranty on colour stability—this means IT WILL NEVER CHANGE COLOUR, no more purple windows. In addition, the adhesive will not distort so you’ll never have to worry about hazy windows or bubbles, ever.
