Abstract
A waxing and polishing apparatus is provided which includes a spherically-shaped body of elastically resilient material and a spherically-shaped housing being adapted to enclose the spherically-shaped body. The spherically-shaped body includes a cavity therein that cooperates with a first portion of the spherical surface of the body to define a wall therebetween; and a plurality of fluid-communicating apertures are provided which interconnect the cavity and the first portion of the spherical surface. A passage is provided which intercommunicates the cavity with a second portion of the spherical surface distal from the first portion and a plug is provided for removably plugging the passage. The spherically-shaped housing includes a first shell of substantially hemispherical shape sized to encase and to conform with a first half of the body, a second shell of substantially hemispherical shape sized to nest on the outside of the first shell, and first and second pivot pins pivotally interconnecting the shells to permit the shells to be relatively positioned to form a spherical case enclosing the body and to permit the shells to be nested to expose a substantially hemispherical portion…
