3M 7000048457 Fine Line Masking Tape 5.0 Mil 3/8 in X 60 Yd

Product Description

The 3M 7000048457 is a green, film-backed fine line masking tape designed for clean paint line separation and precision masking work. At 5.0 mils thick, the low-profile construction seats tightly against surfaces to prevent paint bleed and edge lifting. The specialty-processed film backing stretches for smooth curves while holding steady along long straight runs. Adhesion to steel measures 37 ounces per inch of width, giving the tape firm grip on metal panels and painted surfaces. Auto body technicians, industrial painters, and finishing trades use this tape where edge definition is critical.

This tape is intended for masking applications requiring sharp color separation, including automotive refinishing, fleet graphics, and industrial coating work. The film backing resists moisture and solvents, making it suitable for wet paint environments. It can be applied over fresh paint sooner than paper-backed tapes, reducing the risk of imprint damage during recoat operations. Each roll measures 3/8 inches wide by 60 yards long. Not rated for outdoor exposure or UV environments.
