SailKote on my spinnker sail AND spinnaker tape wont adhere

My spinnaker was treated with Sailkote so that it would launch easily (catamaran). However the sail tape will definitely NOT adhere to the sails. I tried washing with dish soap and rinsed well . Still no sucess. Tried the tape on a non-treated sail and it stuck as It should. Anyone know how to remove the SailKote?
