[Harp-L] XB 40 mouthpiece assembly grease - question

[Blunt White <playharp@xxxxxxxxxxx>]

Converting an XB 40 to Paddy Richter tuning, there is a greasy type of sealant between the comb and mouthpiece.  Would appreciate recommendation on replacement sealant.   The XB 40 is an amazing work of design and manufacturing, hats off to Rick Epping.  The XB is definitely louder than the diatonic, hoping to get up into the mix at the local Irish sessions. Thank you for your recommendation. Blunt White
