The mistake PD mechanics across the country were making is not wadding chewing gum firmly around the screw first, or using Fleers, when any fool chemist could tell you that only Dubble Bubble is gasoline proof (but not ethanol blend).
BTW, don't use an electric drill for the pilot holes. Lost several pals that way. Why do cops actually need cars, anyway? Most donut shops and pizza places deliver.
