Well my experiments to gently (and in one case not so gently) remove the sticky on the binding have pretty much failed.

I got the best results with the not-so-gentle use of a razor blade. Not very satisfactory though. I was able to remove some, but not completely and sometimes it just moved gummy around.

I tried a gentle brush cleaning soap (called Pink Soap) by the mfg. It's what I used to clean my brushes after use with the clear coat. Did not harm the clear coat (good!) did not much bother the gummy (bad).

I also tried lighter fluid. One forum recommended the use of naphtha, which I could not get at the big-box store* But then I saw that it was used in Ronson brand lighter fluid--which I have. So I tried it...only to discover that it (a) wasn't naphtha but rather butane and (b) didn't do any better than the pink soap.
