The acrylic spray sounds like it could work. I'm gonna have to try that.
I volunteered in the Spirit Collection at the museum for a while - smelling alcohol will forever make me think of pickled animals.
If you don't need the specimen to be removed from the jar then you could try fixing it in formaldehyde and then preserving it in ethanol. The colours are a little better then, but formaldehyde is a nasty chemical that you don't want around the house.
Or, if you could fix the surface of the specimen and store it in a nitrogen atmosphere. That's how they keep fruit preserved for out of season sale.
Volunteering at the spirit collections must have been very nice!!!!! I know about the spirit collections and the extensive plant collection of herbariums at Kew. Is great to have someone in here who actually volunteered there.
