One of the things that I found was that being 
exposed to cold, dry air for a short period of 
time will help loosen it and help separate stuck 
items. It seems to work better on stuck layers, 
but I've had a certain degree of success for 
stuck sketches, too. For some odd reason, MKR 
cels seem to unstick the most readily, then 
Studio Pierrot's cels, and then SM. Perhaps 
there's something different from the different 
studios... but I did notice that cels from 
certain series/studios tended to have different 
results. Don't know anything about Dragonball, or 
who puts it out...

You don't want to put it in cold, damp air-- you 
want to keep it dry. And don't try and freeze 
your cel, either. ^_^;; What I did was put mine 
out in my car's trunk, overnight, when the 
temperatures were chilly but not ten-feet-of-snow 
kind of cold. *is in TX*

The next day, I brought it indoors, and began to 
try and separate it. I think the temperature 
changes had some effect on it, because they 
separated very easily. Of course, you have to 
take it slowly no matter what, and be very, very 
gentle. But I sincerely think that the 
temperature change helped. It all depends on how 
much area you have stuck.

And sometimes, you just have to accept that stuck 
is stuck. ^_^
