nope, we still import lime putty
you can find aged fresco lime putty here:

http://FrescoShop.com

as for the "VP" - expended metal (fuond in Home Depot or masonry yard) for base coat is ideal, but adds expence.
a shortcut is using developed base coat materials.

we import a line of italian plasters (that have acrilic binders in a base coat) for our VP projects - dont sell them though.

however you can ask Mitch this question - go to FrescoShop and use contact form:)
