I really like your point about paint acting as a preservative of some sort.
What base of paint might have been used?
How often was it reapplied?
Does one base have more resistance to wind, water , or exfoliation than another?
Every answer leads to an exponential number of questions. Questions that require the input of every side of the Egyptological scisms.
All the more reason for JAWS to be a little more civil in his correspondence.
Thanks for bringing this to the table Bent( it seems that all kinds of bridge building is possible in the name of progress...doesn't it?).
