I got this information sometime ago from another site. Unfortunately I lost it when I got a new comupter.

The historical society needs some photos of markers. Some are quite old. I walk by Jefferson's original marker each day. The writing can be sprayed with something that will highlight the writing without damaging the stone.

Do you know what it is? Thanks.

Art, I don't know the spray you're talking about, but ordinary classroom chalk can be used for the same purpose. Here's an article about it: http://www.neep.dem on.co.uk/mis/photos1.htm.

maybe rock climber's hand chalk might be useful too.
