Never seen it before but it should be just like tint. If I were you go to collision center, myself on the other hand I would use a tint kit from any auto store bc it'll have tools. It prolly came with a tint tool like a card, you take your time and swipe it little at a time... Take your time!!!!
it's just like applying window tint...use a soapy solution to make it easy to apply. although be careful because if you crease it then you might as well buy new tint because i've had bad issues in the past with them not staying once creased. now i just VHT things.
