I  didn't mean to be vague. I was just trying to 
shorten my reply. 

I had the work done by SR Labs. I had them 
separate a few of my LU cels from their sketches. 
LU cels/sketches are notoriously hard to separate 
safely (with no damage to cel or sketch). I have 
yet to see anyone succeed. 

When I say mixed results, I meant that there's 
some good news and some bad news.

The bad news was that there was damage to the 
sketches, though not as severe as if I had tried 
to do it. I think they would do much better with 
other series that do not have such a severe 
sticking problem. 

Another negative was that they were very backed 
up, so it took a long time to get the work done. 
They did let me know beforehand about it, but 
sometimes I get a little impatient.

The good news was that the cels were not damaged. 
The may be one exception in a small spot on one 
cel, but I'm not sure if the problem wasn't 
already there beforehand. 

There was also a pleasant surprise. Although I 
had only asked that the sketches be removed, 
there must have been a misunderstanding and they 
also separated the very stuck cel layers too. I 
had always thought that stuck cel layers were 
impossible to separate without damage. They did 
an incredible job. I do not see any damage at all 
and am very pleased with the results. I wish I 
had known that they were so good at separating 
cel layers earlier. I would have had them 
separate the more loosely stuck layers on a 
couple of my larger cels before I had them 
framed. I am thinking about asking them to 
separate an AS cel with more moderately stuck 
layers, since it has some white mineralization 
starting to form in one of the air pockets. 

Anyways, that's what I meant by mixed results.
