From someone who paints and installs decals if your going to try this route I suggest you keep moving and dont stay in one place. You had also have a good grip on the drill or your going to end up with it making marks on the paint.
Make sure you wax the area you just removed the decal from.
Be careful if you choose the chemical or liquid cleaner, some can be very harsh on paint.
