3M™ 218 Masking Tape is a 5.0 mil green polypropylene film tape with a rubber-based adhesive, engineered for precision masking where clean paint lines and tight dimensional tolerances are non-negotiable. The 1/8-inch width delivers the narrow profile required for fine detail work that wider masking tapes cannot achieve.

This tape is a proven choice for automotive refinishing, industrial spray and bake finishing cycles, silkscreen registration, pinstriping, and lettering work. The polypropylene film backing resists solvents and moisture, keeping edges sealed during chemical exposure, while the 250°F rating for up to 30 minutes makes it compatible with standard paint bake ovens.

The rubber adhesive bonds firmly to painted, metal, and primed surfaces and releases cleanly without tearing the backing. Residue performance will vary by surface and dwell time; test on sensitive substrates before full application. Each case contains 3 rolls and ships via parcel carrier.
