Has anyone used the Breathing color varnish for rag papers and canvas media? What does 
it do to the surface and the d-max?

They also sell a rag paper called Elegance. On their website they talk about how many rag 
papers have an acid based coating, but theirs is a neutral ph. This is the first I've heard of 
that. What's that all about?
