Recyling garden plaques with acrylic paints

My girlfriend Pam from Wisconsin had gifted me these beautiful yard plaques several years ago. This summer I just gave them a fresh coat of acrylic paints and one coat of UV protective spray, and they are fresh spankin' new ! Whooo ! Acrylic paints will withstand the rigors of Kentucky weather. But Wisconsin weather ? You'd probably have to do several coats of fixative spray Krylon for optimum preserving.
