I've removed covers before from other mfr's and they have used silicone to hold the covers in place - was a right pain to get off a ruined the finish on the coils.Good news is that BKP use beeswax so it's easy to clean off the mess - some kitchen-roll is all you need. I've done this a couple of times with BKPs - the Cold Sweat is my LP had covers, but Tim did the removal on that one.According to Tim, the standard colour for covered humbuckers is double black - it will only be different if specified when ordering.
