Starting on the wide end (top side) of the Scoop use a Hair dryer(on High heat) around 1 inch away. Or a heat gun (On low heat) with a lot of distance around 8 to 10 inches away from the Scoops where the 2 sided tape is installed on the edges. Get some strong fishing line (10 lb test or higher) and you Scissor back and fourth between the scoop and the car . If it is hard to scissor if off then you need to heat a bit longer. Dont try and heat the whole scoop at once. Just the area you are working on. Be very careful with a "Heat Gun" because you might really mess up the paint on the Scoops and even your car. Keep the flammable adhesive remover away from the heat gun and hair dryer. In fact put it away until you have removed the scoops.
Be patient with it. Then Goof Off or Mineral Spirits to remove any residual tape adhesive left on the car. Whatever you use to clean off the tape adhesive should be tested somewhere on the car you will never see. This insures you will not mess up your paint if you are using the wrong cleaner. (Lacquer thinner will ruin the paint)
This removal method will not leave scratches on your car.
It works great but you can't rush it.
