Finishing and... Insects.

I've made an insect case. One of those picture frames with relief between the glass and the backing so that you can pin insects onto the backing and then put them on display in the frame behind the glass. You know the ones.

Anyway, my plan is to finish the inside of the case the same as the outside. Likely four coats of oil blend finish, fully cured, and then finished off with a top coat of carnauba wax.

So, aesthetics aside, I'm looking for any feedback about the way in which this finishing technique could affect the bug which will ultimately be preserved in the case. Any reason to think that this will degrade the bug? Preserve the bug?

Any kind of feedback appreciated.

Thanks a lot in advance.

Cheers,
Luke
