A 2006 that's in for transmission repair. I don't have my notes in front of me, but I think there is rust in all the old cylinders. Some have a lot more rust than others. I'm sure it is caused from the GoldWing being stored for extended periods of time, and the prior owner not following the storing procedures as stated in the Owner's Manual.
As someone who retired out of Honda, working at the Anna Engine Plant (AEP), in machining, those pictures sure brought back memories. But that is the first time I have ever heard/see of this 'cosmoline'.
