Rebound® is processed and applied in the same way it was on the first application of the mold. Rubber keys are once again placed on the curing Rebound® to help the mold rubber register inside the Free Form® Air shell. Once all the layers of Rebound® have been applied, the rubber is once again cut and the cardboard sides are reassembled around the model.
Ease Release® 200 (Although the Ease Release® 205 used previously could also be used) is used to make sure that the new application of Free Form® Air will not bond to the first layer of Free Form® Air when trying to separate the two halves. A liberal coat of Ease Release® 200 is sprayed onto all surfaces.
