My local shop had the same problem with the weights not sticking to the powdercoat because I put a few layers of sealant on the wheels before they mounted the tires but they wouldn't have done something that dumb. They told me it might take awhile for the tape to really stick so once I got the wheels home (they didn't install the wheels on to the car for me) I should try to apply some pressure to the weights with some C clamps or something similar for at least a few hours. I ended up using a rubber padded large vise grip type tool and never had any problems with the weights falling off.
