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.

What is claimed is: 1. A method for producing a multi-color polymeric component using an in-mold coating process, the method comprising: applying a contact member having a flexible seal to a surface of a mold such that masking material is captured between the flexible seal and the surface of the mold, and such that the flexible seal conforms to the shape of the surface of the mold to form a seal between the masking material and the surface of the mold, the masking material covering a first portion of the mold; spraying a polymeric coating having a first color on a second portion of the mold; moving the contact member and the coated masking material away from the mold, thereby uncovering the first portion of the mold; spraying a polymeric coating having a second color on at least the first portion of the mold; applying a polymeric bonding material to at least a portion of each coating, thereby integrating the coatings and the bonding material; and retracting an amount of coated masking material, thereby dispensing an amount of uncoated masking material and facilitating production of another multi-color component. 2. The method of claim 1, further comprising tensioning at least a portion of the masking material. 3. The method of claim 1, wherein the flexible seal is inflatable, and forming a seal between the masking material and the surface of the mold includes inflating the flexible seal. 4. The method of claim 1, wherein retracting an amount of coated masking material includes rotating a take-up roll to receive the coated masking material. 5. The method of claim 4, wherein rotation of the take-up roll is motorized. 6. A method of masking a mold to facilitate a multi-color spray molding process, the method comprising: dispensing an amount of masking material from a supply roll; receiving an amount of masking material onto a take-up roll, the supply roll and the take-up roll cooperating such that masking material dispensed from the supply roll can be received onto the take-up roll; and disposing a portion of the masking material proximate the mold, to protectively cover at least a first portion of the mold, including: applying a contact member having a flexible seal to a surface of the mold such that masking material is captured between the flexible seal and the surface of the mold, and such that the flexible seal conforms to the shape of the surface of the mold to form a seal between the masking material and the surface of the mold. 7. The method of claim 6, further comprising: spraying a polymeric coating having a first color on a second portion of the mold; moving the contact member and the coated masking material away from the mold, thereby uncovering the first portion of the mold; spraying a polymeric coating having a second color on at least a first portion the mold; and applying a polymeric bonding material to at least a portion of each coating, thereby integrating the coatings and the bonding material. 8. The method of claim 6, wherein the flexible seal includes an inflatable seal, and the step of applying the contact member to the surface of the mold includes inflating the inflatable seal such that the inflatable seal closes a gap between the masking material and the surface of the mold. 9. The method of claim 6, further comprising tensioning at least a portion of the masking material between the supply roll and the take-up roll. 10. The method of claim 6, wherein the receiving an amount of masking material onto a take-up roll is effected by a motor operable to rotate the take-up roll.
