The original model is made of urethane plastic. Begin by hot gluing the original model to a working surface. Spray both the model and board with a coating of Ease Release® 200 release agent. Measure EZ ~ Mix® 40 Parts A and B in equal amounts by volume and combine in a mixing cup. (It is recommended that you wear rubber gloves during this proces.) Add So-Strong Red color tint to the rubber, which will help to ensure thorough coverage is achieved over the white model. Begin brushing the EZ~Mix® 40 onto the top of the model and work your way down. Apply the first layer thinly to ensure that all detail is captured. Create a 3 in (7.6 cm) flange. After 1 hour when the rubber is tacky, mix and apply a second untinted batch of rubber.
