Controlling graffiti on unsupervised wall paintings

I am currently examining a fragmentary medieval wall painting in a
ruined 14th century church. Most of the painting is still hidden
beneath layers of limewash and at present there is no intention of
uncovering it. The church is in a very isolated position and access
cannot be controlled. As a result, extensive vandalism has occurred
including widespread graffiti (both carved and applied by spray
paint). The body who owns the building wish to reduce the aesthetic
disruption caused by the graffiti, particularly in view of its
obscene nature.

While the removal of the graffiti from the surface of the wall
painting is technically possible, the situation of the church is
such that it is likely to reoccur almost immediately. Therefore
other alternatives are being considered. Most of these involve the
use of a shelter coat or a similar treatment, applied regularly as
part of a long term programme. The advantages of such a treatment is
that it is simple and relatively inexpensive and does not compromise
the wall paintings which will remain covered. However, this will not
prevent the graffiti from reoccurring.

I would be very grateful to hear of case studies relating to similar
situations, particularly those with innovative solutions.
