I used a hair dryer and once I could push up a corner slightly with my finger nail, I then used a pair of tweezers to get a good grip and they all came off in like 5 minutes. No residual glue was left either
Just be patient with the hair dryer and not too close to the paint. Once you start pulling with the tweezers, keep waving the dryer about 6 to 8 inches away and it comes of easy.
