My (admittedly limited) understanding of plastination is that you
are replacing some chemical components of an object/organism (mostly
the most fluid and rot-able bits) with other, polymerizable
components, that are less prone (but not immune) to decay. This
means that you are not left with the original object but a copy of
the shape of the item. While this is a valuable tool for some
purposes, it is more in the realm of restoration than conservation.

I would be hesitant to use this technique with bog bodies, where
there is so much more of interest than just the shape of the body. I
think it would still be a useful technique in other areas, such as
natural history collections, where it is the shape of a specimen
that is the point of interest, and the ability to handle the
specimen is of value. With bog bodies, however, I think there would
be too much loss of information for it to be a useful technique.
That's just my opinion though.
