around the window stickers

i removed it from my van it took me about 5 hours to do it, i used a heat gun and pliers (make sure to put the heat gun in the lowest setting otherwise you r gonna be burning your fingers, the worst part was removing the sticky stuff that was left behind, i used a lot of different stuff to remove it (wd 40, brake cleaner, throttle body cleaner, this last one worked best, spray it on and remove with a razor blade(IF YOU PAINTED YOUR CAR DO NOT USE ANY ABBRASIVE CHEMICALS TRUST ME IT WILL EAT YOUR PAINT).
