Someone out there must have DamppChaser's email address. DamppChaser can tell you where you can get their products. With a piano as big as the Imperial 2 25 watters are not likely to cause any dampage, unless they are mounted under and agains the pinblock. There is no fire hazzard at all unless the chords are frayed. Protek is a long chain polymer designer product forulated to Protect, Clean and Lubricate bushings, flange and key. It is rather dear here, but a little goes a long way. It is, as far as I know, non flamible, but I have no idea how to get some over there. That bearing seems excessive. Little is better than more. Check the angle agains the top of the bridge and how the string goes to the plate and hitchpins. Hope this is helpful. Newton nhunt@jagat.com
