Aviation-grade marking supplies have shifted toward more specialized, high-contrast pigments that resist smearing during critical inspections. I have analyzed these options by weighing technical specs against common user feedback to see which ones actually perform under pressure. My ranking reflects a focus on gear pattern clarity and ease of cleanup. Read on to see which marking agent earns the top spot for your workbench.

Choosing Between Them
For your bench, I recommend the Motive Gear GMC1 because it offers the perfect balance of thickness and clarity for precision gear setup. If you struggle with visibility, the Trident U-Mark IT Green is the best choice for high-contrast needs, while the Rustoleum Inverted Paint handles large-scale jobs with ease. I would choose the Trident U-Mark IT Yellow only if you prefer a liquid application and have the time to let the paint properly set.
Be aware that these products serve different roles: liquid paints are generally better for rapid marking, whereas thicker pastes are superior for fine-tuning contact patterns. Always check your surface cleanliness before application, as even the best gear marking agent will fail if the metal is coated in old oil or debris.
