I really would like to know where those two C8's have been all these years. There are probably good stories they could tell, if only they could speak. It's a shame that such wonderful, expensive telescopes were not kept in better condition.
The problem you see in these early C8's was caused by the primer. There was an incompatibility between the green primer and the paint. The primer is bleeding through the paint. After this happens the paint feel sticky to the touch.
