A masking system is provided that includes a supply roll of masking material, supported by a first roll support. The supply roll is rotatable on the first roll support, which allows the masking material to be dispensed. A take-up roll is provided to receive masking material after it has been used. A masking arm is positioned on an inside surface of the masking material, and contacts a portion of a mold to capture the masking material between the masking arm and the mold, thereby sealing off a portion of the mold during a coating process. After the coating process, the take-up roll is rotated, thereby dispensing new masking material from the supply roll.
