Simplify painting and weathering car wheels (and keep your hands clean!) with these precision laser-cut masks. Designed for Kadee(R) wheels, the masks will hold other brands of 33" or 36" HO wheels with NMRA RP-25 profiles. Each holds four wheels at once, covering the treads, but leaving the backs, fronts and axles exposed. After painting, simply pull each "finger" to release the wheelset. Made of acrylic, the mask can be cleaned in most paint solvents, and wiped clean for years of use. Each mask kit consists of five acrylic parts and can be assembled in minutes using solvent type glue for plastics (sold separately).
