Thin sections of waterlogged wood

I'm about to begin sampling and making thin sections of waterlogged
wood from the mid 18th C Sadana Island Shipwreck, an excavation by
the Institute of Nautical Archaeology-Egypt.  I've had practice
making thin-sections in a glycerol medium for immediate inspection
and photo-micrography, but I need to make these permanent slides for
future reference.  Can anyone give me advice on how to make these
permanent? Is it enough to seal the edges of the cover slip with
some resin, such as Canada Balsam or Paraloid B-72?
Thanks for your help,
