Personally, I am not a fan of static cling vinyls for store window graphics...too many conditions can go wrong or not work for the (usually) customer applied signage....I reserve static cling stuff for car sales lots on their vehicle window prices...
For Holiday graphics, multicolor splashes, I use Oracal 631 removable matte white for the "base" with cheap calendered vinyl colors overlayed on top....Given the graphics will be up for near 2 months, they look bright (gotta have a white or pastel colour base), and window cleaners that market the store on a weekly basis won't harm the graphics...Oracal 631 is easily removed when the season is over....Surely reckon there are other brands of "removable" exhibition vinyl that could be used also....
