This is a softening agent for slidemarks. It has the effect of closely adhering slidemarks to curved surfaces. Directions for Use: First apply a quick drop to the area where the decal will go using the brush attached to the cap. Apply decal over it. Apply gentle pressure to the decal with a soft cloth removing any excessive liquid and sticking the decal down fast. The decal will stick perfectly even on uneven or curved surfaces. If air gets in between the decal and the model surface after drying delicately prick the decal with a needle and insert Mr.MARK SOFTER through the resulting hole. The air will escape and the decal will stick down firmly.
