3M 7000123578 Fine Line Masking Tape 1in X 36yd 5.4 Mil

Product Description

The 3M 7000123578 is a high temperature fine line masking tape designed for precision paint masking in demanding finishing applications. Built on a conformable vinyl backing at 5.4 mil total thickness, it delivers clean, sharp paint break lines on curved and contoured surfaces. The tape measures 1 inch wide and comes in a 36-yard roll, providing substantial coverage per roll for production or shop use. Automotive painters, body shop technicians, and industrial finishing professionals reach for this tape when a crisp demarcation line is non-negotiable and heat from paint curing ovens is a factor.

This tape is suited for fascia panels, rocker panels, two-tone finishes, and other multiple-color applications where the paint break line must be exact. Its vinyl construction allows it to conform smoothly to body contours and compound curves without lifting or flagging during application or baking. It is used in automotive refinishing environments as well as industrial coating operations that involve elevated temperatures during the cure cycle.

Key Features

• Vinyl backing conforms to curved and contoured surfaces for clean paint edges
• 5.4 mil total thickness provides durability without bulk
• 1 inch width suits standard fine-line masking tasks on panels and transitions
• 36-yard roll length reduces mid-job roll changes in production settings
• High temperature rated construction withstands paint oven cure cycles
• Blue color provides easy visual contrast against painted and primed surfaces

Compatibility

Designed for use in automotive refinishing and industrial coating applications requiring critical paint break lines, including fascia, rocker panels, two-tone, and multiple-color masking work.

Installation Notes

Surface must be clean, dry, and free of dust, oil, or wax before applying the tape. Press the tape edge firmly and uniformly along the masking line to prevent paint bleed. Remove the tape at the angle and pace recommended for the coating system in use to avoid lifting or chipping the finish edge. Follow the paint manufacturer and oven manufacturer guidelines for maximum allowable temperatures during cure.
