Slot car track
Every slot car enthusiast knows: Too much oil is harmful. Therefore workarounds like small toothpick tips, linty cotton swabs and Q-tips, and other unsuitable tools are commonly seen for oil application.
This is not necessary anymore. Any spot can be reached with the Sommerhoff Precision Oiler Pen and provided with as much oil as exactly required. Oily toothpicks and Q-tips smudging the workbench are past and replaced by the absolutely clean and leakproof Oiler Pen. The mechanics remain perfectly movable and nothing now should stand in the way of the next lap record.
