New px-160, glue in between some keys

[Cknorr]

I just received my px160 today. It plays and sounds great. I just have one concern. There seems to be glue in between some of the keys on the lower end. It doesn't affect the sound or action as far as I can tell. I just wanted to check if this was somewhat normal or if it is something I should be concerned about?

 

I have pictures if that would help. Thanks.

Glue? They use white grease in the action.  Is that what you are seeing?  Or actual hardened glue?

It must be the grease. Thanks!
