One of the compartments has a stencil formed therein which may be in the form of holes punched in one wall of the compartment arranged to form a desired marking image which may be letters, numerals or symbols. In lieu of punched holes, the images may be formed by slots in this compartment wall. Removable tape is placed over the holes or slots. One of two fluid components is placed in one compartment and another of two fluid components is placed in another compartment which may or may not be the compartment having the images formed therein; these two components forming an etching or marking material when combined together. When it is desired to perform the etching operation, the separator means is mechanically actuated to remove this sealing separation between the compartments such that the fluids are mixed with each other thereby forming the etching or making medium. The tape covering the holes or slotted portions forming the marking image is removed and the stencil is placed against the surface…
