The Southland Glass, Crystal, and Bronze Turkey Call Surface Conditioner is a great way to custom tune and clean your glass, crystal or bronze surfaces and striker ends.
The glass, crystal and bronze calls can be very difficult to deal with since most of them do not come pre-conditioned when you buy them new. If your new call comes and looks as slick as well, glass, then you will have to condition it before you can expect to get any sounds out of it.
