A method for manufacturing a coated object and a coating substance spreading apparatus, which coat, as uniformly as possible, a coating substance on a curved coating target surface are provided. A method for manufacturing a coated object, the coated object being an object coated with a coating substance on a coating target surface Tf of the object T, the coating target surface Tf having a curved surface, includes dispensing the coating substance onto the coating target surface Tf; and revolving the object T, having the coating substance dispensed onto the coating target surface Tf, about a revolution axis 13a located remotely from the object T.

Stobe Spin Art is a new Apparatus for making traditional Spin Art, that employs precise stroboscopic Illumination upon a spinning substrait, held safely captive in an appropriate platen, such that the spinning substrait, timed to stroboscopic illumination of specific luminosity and duration appears still to the Artist's eye during the artistic process, allowing that artist to create, observe, modify, and finish their work of art in real time. That artistic process uses a variety of pigments, specific to individual substraits, and employs specifically designed depositors, including deposition pattern dies, for different creative effects. Substraits will vary as will their specific pigments, (paints, inks, dyes, and glazes, etc.) depending upon the application, specific to the substrate. The Apparatus will feature the use of U.V. curable pigments, and a safe U.V. Interlock to quickly cure the artist's finished work of art into a smear free take home masterpiece.
