Dial-In Pocket Window Marker White .5oz Bottle

The Dial-In Pocket Window Marker White .5oz Bottle from GEDDEX is a precision marking tool designed specifically for automotive technicians and vehicle modifiers who need to document baseline settings, timing adjustments, or component positioning during engine tuning and calibration work. Whether you're dialing in carburetor settings, marking ignition timing on a distributor, or establishing reference points for suspension geometry changes, this compact white marker delivers permanent, easy-to-read marks on glass, polycarbonate, and rubber surfaces without causing damage or leaving residue that compromises visibility.

The 0.5 oz bottle includes an integrated applicator that provides controlled, fine-line application—critical when marking small gauge faces, window markers on fuel bowls, or precise reference lines on intake manifolds and cylinder heads. GEDDEX formulated this marker to be safe on glass, polycarbonate, and rubber, eliminating the risk of chemical damage to gauges, sight windows, or protective trim during extended dial-in sessions. The compact dimensions (0.7 x 0.65 x 4.8 inches) and lightweight design (0.07 lbs) make it pocket-friendly, so you can carry it from the engine bay to the dyno without adding bulk to your toolkit. The white pigment contrasts sharply against most engine components and gauge backgrounds, ensuring marks remain visible under shop lighting and through the inevitable grease and heat cycling of performance tuning.

Experienced mechanics, engine builders, and drag racing crews benefit most from having the Dial-In Pocket Window Marker White .5oz Bottle on hand during baseline establishment, carburetor synchronization, timing verification, and any procedure requiring visual alignment marks that must survive thermal cycling and multiple ignition cycles. This marker is indispensable for domestic and import engine work—from classic carbureted platforms to modern fuel-injected systems where precision reference marking directly impacts tuning accuracy and repeatability during dyno pulls and street validation.
