I finally got my dream Washu cel today, and I 
have a question about the douga on the back.

The douga is not stuck, and I prefer to keep it 
that way. Right now, the paint on the back of the 
cel is touching the non-matching douga. Would it 
be better if I put a sheet of clear polyproplene 
plastic between the two, to prevent the cel from 
sticking, or would it then stick to the plastic? 
I have the cel and drawing in a cel bag to 
protect them, which is in turn inside my cel 
book. Im just not sure wether its better to have 
the cel paint touch plastic or paper.

One other quick question, if anybody knows. Are 
the dougas with cels Acid Free paper? Would it be 
better to put a sheet of acid free paper behind 
the cel, instead of the douga?

Thanks for anyone's help!

PS, Ill scan my new cel this weekend, and post it 
on the forum here!
