Perpendicular Parking lot parking spaces; HO scale lanes are approx. 1.25" wide and 2.375" deep; arrives unpainted with a white, versatile plastic finish only. I use a "stampin''" chalk marker purchased at stampinup.com under ink/markers. Tape down the template onto the desired location using blue painter's tape. Trace each lane line with the stampin chalk marker. The marker ink drys quickly and you may want to re-coat it a few of times.
