Method of creating a design on a helmet

Abstract

A method of creating a design on complex curves and irregular contours of a protective helmet, quickly and without having to first disassemble the helmet. A design is transferred to a clear film/acetate, which is then exposed onto a photoresist mask, transferring the design to the photoresist mask. The mask is washed out creating blast-able areas in the design mask. The mask is adhered to an area of the helmet, which is otherwise covered with a sealed protective bag. Sandblasting/abrasive-blasting etches portions of the helmet surface through the blast-able area of the mask. Various colors or other special effects may be painted/applied onto the etched portions of the helmet surface. The protective bag and photoresist mask can be removed, and the painted areas buffed/polished in a final step.
