I have a LU cel from the same sequence as yours.  
Won it at ebay for a hefty price and received it 
damaged (the seller made no mention of the fairly 
extensive damage).  After I calmed down from 
seeing the damage, I decided that I had wanted a 
cel from that sequence for SOOOOO long that I 
couldn't let it go.  I figured since I also had 
an illustration degree I could fix it myself ... 
color matched it and everything.  Wouldn't you 
know it, the colors blended just right and the 
cel looks as good as new (so to speak).  And 
before I get flamed ... I do NOT necessarily 
recommend people handling their own 
restorations.  Color mixing to match the studios 
colors can be especially difficult (I can image 
how hard some of the f/x colors would be) and if 
you don't do it right you might be INCREDIBLY 
disappointed.  So if you're not confident don't 
do any touch up work and go see a professional 
cel restorer.  

I just wanted to share my success ... sorry for 
the long post.
