Mark surfaces with handwritten messages, designs, or logos. Draw your message on stencil paper using a scriber or other sharp point, then place the stencil on your metal marking surface. To transfer the message, wet the pad on the etcher with etching solution and press it over the stencil, then touch the grounding wire to your marking surface to activate the solution. Marks are black. Use the included DC voltage adapter clip to make clear and frosted marks.
