WOW, you guys!  I just got a letter back from one 
of the places I wrote to, SR Labs.  His 
restoration studio has worked with animation 
studios in Japan, Korea, and everywhere in the 
world. He says the line fading and problems with 
Japanese animaion cels are very familiar to him, 
and he has been working on them for decades.  
He's going to send me a lot of information about 
it though the mail.  Anyways, so I can stop 
bothering everyone on here with this stuff, if 
anyone wants anymore detailed info about what I 
learn, please feel free to email me!  This stuff 
is really fascinating, and I think many of you 
would benefit from it.  If anything you can file 
it away in your brains and impress people at 
gatherings and cons with your extensive cel 
knowledge ^_~*  Thanks for listening to me 
blather!
