Thanks!
I wonder what the WD40 ingredient is?
I generally use paraffin oil on specimens, as it is colorless,
scentless, inert, doesn't braek down and protects the shell from
airborn acids (especially important when specimens stored in
particleboard-based cabinets, which release formic acid). BUT it
din's stop the Exilia fading. Might just try WD40... this could be
applied along with paraffin.
I have found a good way to keep periostraca soft and prevent peeling.
Especially important for hairy or velvety ranellids and capulids. I
use the same mix I use for preserving chitons... glycerine dissolved
in ethanol. Just remove any excess. It's water-soluble, so can easily
be soaked out if necessary. Useless for treating shelly surfaces, as
it does not soak in at all.
