well yes when its cold the vinyl is less plyable, thats why you use a hairdryer or a good heatgun to form it around corners and stuff but ours have soo many contours (punn intended) its too hard to do, i tried like 8 times on mine and couldnt do it, my vinyl guy said he could do it but would take some time. i can do vinyl pretty well myself but eyebrows on our headlights is a no go for me
