Hello, John.
I'm very sorry to hear this. Kling-On does claim that they can be removed and reapplied without any trouble. I've updated XGuitars.com with a warning that these can damage your finish.
Would you like for me to contact Kling-On on your behalf to see if they'd be willing to have this repaired for you?
Also, do you know what kind of finish is on your instrument?
Best regards,
Geoff
