Abstract
Manufacture of ornamental vehicle wheels wherein a mold surface of desired decorative contour is sprayed with one or more layers of a polyurethane reaction mixture and partially cured in situ. A steel wheel is then placed over the mold surface and a polyurethane reaction mixture which includes a foaming agent is poured into the mold cavity formed therebetween. The poured mixture is then cured and the layers are finish-cured in situ to form an integral ornamental elastomeric structure adhered to the wheel.
