Hello John,

I fear i can't be of great help, although I would love to help you in practise, but I read this book about restoring fresco's, a sort of bible in my opinion, with lots of clear pictures in it and all that can be wrong with fresco's explained in it and suggestions as well of how to repair it. In most cases it seems not too difficult to do so (but i am not a professional restorer)

It is written by two italians and someone from Belgium,
P Mora, L Mora and P Phillipot (or maybe philippot, I can't remember) . It is called `conservation of wallpaintings' and it's from 1994.

i hope you will succeed to convince the council.
