I have a Korean grand with the common problem of glue migrating into the flange bushings. The jacks are giving me trouble, one often another, and it is embarrassing to have to keep returning (always for a newly sticking jack). The question: Has anyone had any long term trouble (as long as this has been available) with CLP on 2-piece jacks? I am suspecting that this product is either silicon oil or teflon in a kerosene base. Does the residue cause trouble with the glue joints of the jacks or other parts? Blaine Hebert
