Thats the only solution, heat the dam thang up with a hair dryer.....then very slowly peel it by hand......for the blade thing, dont do it yourself....go to you local car market, find a guy who does window tinting, these people are experts with the blade, ask him to remove the stickers with the blade, he`ll know where to put pressure an how much an also wont destroy the paint........if you want to save money, just keep on hearting the same spot with a dryer till it losses its sticking property an loosens enough for you to peel it off. Remove the excess with wax...just apply wax to the spot an rub it slowly.
