3M 7000048446 Fine Line Masking Tape 4in X 60yd 5.0 Mil

Product Description

The 3M 7000048446 is a green, film-backed fine line masking tape engineered for precision paint line work and general masking applications. At 5.0 mil thick, the tape maintains a low profile that promotes sharp, clean color separation at paint edges. The specially processed film backing stretches to conform smoothly around curves while holding firm on long straight runs. Adhesion to steel is rated at 37 oz per inch of width, providing secure hold without lifting during spray or brush application. Licensed tradespeople and auto body professionals rely on this tape where crisp edge definition and moisture resistance are required.

This tape is suited for automotive refinishing, industrial coating, and general masking tasks where clean paint lines are critical. The film backing allows application over freshly painted surfaces sooner than conventional paper tapes, reducing the risk of imprint damage to underlying coats. It performs well in environments with solvent or moisture exposure but is not rated for outdoor or prolonged UV exposure. Each roll measures 4 inches wide by 60 yards long, making it appropriate for both large panel work and detail masking.

Installation Notes

Apply to clean, dry surfaces free of oils, dust, or loose coatings for best adhesion and edge definition. Remove the tape promptly after painting while the coating is still slightly tacky or fully cured per the paint manufacturer guidance to minimize edge lifting. Do not expose this tape to outdoor conditions or direct sunlight during use. This product is intended for professional application by trained refinishing or coating technicians.
