Rebound™ 25 will be used as the mold making rubber. Rebound™ is dispensed 1:1 by volume and mixing in a clean mixing container to an even color consistency. Once it has been mixed thoroughly, the Rebound® is brushed directly onto the rifle and clay bed. Once the entire gun is covered in a layer of Rebound™ 25, it is allowed to set up prior to adding the second coat.
