3M 7000123383 Fine Line Tape 215 Blue 0.75in X 60yd 4.8mil

Product Description

The 3M 7000123383 is a film-backed fine line masking tape designed to produce clean, sharp paint lines on highly contoured and irregular surfaces. At 4.8 mil total thickness, the tape maintains a low profile that minimizes paint bleed and edge buildup. It conforms around corners, into depressed areas, and along complex body contours without lifting. The smooth film backing allows application directly over freshly cured acrylic lacquer, enamel, and polyurethane finishes. Rated for use up to 250 degrees F, it holds its bond and line definition under elevated paint booth temperatures. Supplied in a 0.75-inch-wide by 60-yard roll.

This tape is suited for automotive refinishing, industrial coating, and sign painting applications where a precise color separation line is required on curved or irregular substrates. Body shop technicians and industrial painters use it when standard crepe-backed masking tape cannot conform tightly enough to the surface geometry. It is intended for indoor use only and should not be used in outdoor or prolonged UV-exposure applications.

Key Features

• Low-profile 4.8 mil thickness reduces paint edge buildup for a clean color line

Compatibility

Designed for application over freshly cured acrylic lacquer, enamel, and polyurethane paint systems on automotive and industrial surfaces. Not intended for outdoor or UV-exposed applications.

Installation Notes

Surface must be clean, dry, and fully cured before applying tape. Press the tape edge firmly along the desired paint line to ensure full contact and prevent bleed-through. Remove tape at a low angle while the topcoat is still slightly warm for cleanest edge release. This product is intended for use by experienced automotive refinishing technicians and industrial painters familiar with masking procedures.
