OMG! You are a genius man! Simply wrap the tape around it, hold the gill with a micro fiber towel, wriggle the gill in the towel and pull hard on the tape. I changed both sides in 10 minutes! Holy crap, to think of people ripping out their fender liners and prying these things off with a screwdriver... This method there was no way you damage anything. They pop out, but not violently, very easy to control and no chance of damaging the paint or the gill.
This board should have reputation points like 6 speed. You certainly earn some with this.
