Index Cards - Gray (3'' X 5'')

Rite in the Rain index cards in gray (3'' x 5'') are purpose-built for mechanics, technicians, and field professionals who need reliable documentation in demanding conditions. Whether you're tracking maintenance logs under the hood, jotting down diagnostic notes in wet shop environments, or keeping job records in your toolbag, these all-weather cards deliver legibility and durability where standard paper fails. The compact 3x5 format fits easily into shirt pockets, glove boxes, or work aprons, making them an essential addition to any automotive professional's daily kit.

Manufactured with premium 100# paper weight, Rite in the Rain index cards resist water, oil, grease, and harsh shop chemicals without bleeding or deteriorating. The universal pattern printed on the front accommodates any note-taking style, while the blank reverse side offers flexibility for sketches, part numbers, or quick reference diagrams. This proprietary all-weather paper technology remains readable even after exposure to moisture, mud, and temperature fluctuations—critical for mechanics working outdoors, near steam bays, or in uncontrolled environments. At just 0.4 lbs and measuring 5 x 0.88 x 3 inches, the entire pack remains lightweight and portable.

Mechanics performing engine rebuilds, transmission diagnostics, or frame repairs benefit most from these durable cards as an alternative to clipboard notes that smudge or deteriorate under shop conditions. Technicians working on vintage restorations, marine engines, or agricultural equipment find the moisture-resistant design invaluable for tracking multiple jobs simultaneously. Fleet maintenance supervisors and independent shop owners use them to document repair history, parts sourcing, and customer communication in a format that withstands the rigors of the workbench. Compatible with any pen or pencil, these index cards integrate seamlessly into existing service documentation systems and outlast conventional cardstock by years in active shop use.
