3M 7000048630 Fine Line Vinyl Masking Tape 3/8 in X 36 Yd

Product Description

The 3M 7000048630 is a high temperature fine line vinyl masking tape engineered for precision paint masking in automotive and industrial finishing applications. Sold as a single roll measuring 3/8 inches wide by 36 yards long at 5.4 mil thickness, this tape is designed to produce sharp, clean paint break lines. The vinyl backing conforms to contoured surfaces while resisting bleed-through at elevated cure temperatures. Licensed finishing professionals and body shop technicians rely on it where crisp color separation and edge definition are non-negotiable on production or refinish work.

This tape is suited for masking fascia panels, rocker panels, two-tone paint layouts, and other multi-color applications that demand accurate, repeatable paint break lines. It performs in spray booth environments where heat from bake cycles can cause conventional masking tapes to lift, bleed, or leave adhesive residue. The fine line profile keeps the tape edge thin enough for tight radius curves and body contour transitions common in automotive refinishing.

Key Features

• Vinyl backing conforms to curved and contoured surfaces without lifting
• 5.4 mil total thickness supports a clean, defined paint break line
• High temperature formulation resists paint bleed and edge lift during bake cycles
• 3/8 inch width suited for fine line masking on fascia, rockers, and two-tone splits
• 36-yard roll length reduces mid-job splicing on longer panel runs

Compatibility

Designed as an OEM-style fine line masking tape for automotive spray booth and refinishing environments where high temperature paint masking is required.

Installation Notes

Application is performed by trained automotive refinishing technicians or industrial painters. The surface should be clean, dry, and free of contaminants before tape is applied to ensure adhesion and prevent paint migration under the edge. Press the tape edge firmly and consistently along the intended paint break line before spraying. Remove the tape at the appropriate stage of cure as recommended by the paint system manufacturer to achieve the cleanest edge release.
