Wonderflex Pro is a smoother, glossy, unreinforced version of Wonderflex that because of its smooth surface and ability to stretch, can even be pressed into silicone molds. This material is softened in water heated to 160 degrees F (71 C) prior to application. When use of water is impractical, an industrial heat gun may be used to soften the material. Wonderflex Pro softens in 30 seconds and provides 2-4 minutes working time. Available in 43" X 55" precut sheets.
