Tape Fine Line 1/4" x 60YD #265 Roll/Each - 3M Automotive

Part #: 31798

The 3M Automotive Fine Line Tape #265 (Model 31798) is a high-performance masking tape engineered for professional technicians and mechanics requiring precise color separation in demanding applications. Featuring a durable polypropylene backing and a specialized silicone adhesive, this tape is designed to deliver sharp, clean lines and reliable adhesion, even on challenging surfaces. Its thin profile and conformability make it an essential tool for intricate masking tasks in automotive and industrial settings.

Key Features

  • Exceptional Gel Coat Color Separation: Designed for in-mold fine line masking, providing superior color separation in gel coat applications.
  • Superior Chemical Resistance: The polypropylene backing offers robust resistance to gel coat chemicals, outperforming traditional vinyl tapes.
  • Reliable Adhesion: Equipped with a pressure-sensitive silicone adhesive that delivers immediate and reliable hold, even on molds treated with high-slip release agents.
  • Conformable Yet Strong: The polypropylene backing is stiff enough to pull sharply and evenly through gel coatings, yet conformable for smooth curves.
  • Moisture and Solvent Resistant: Maintains integrity and adhesion when exposed to most solvents and moisture.
  • Easy Unwind and Application: Engineered for smooth unwind from the roll, minimizing stretch and ensuring consistent application.

Applications

This fine line masking tape is particularly suited for professional use in scenarios demanding precision and durability. Common applications include multi-color gel coat masking involving fiberglass, such as in boat building for hulls and decks. It is also ideal for specialty vehicle and marine gel coating projects, as well as composite manufacturing for items like showers, tubs, countertops, and vanities. In automotive refinishing, it excels in creating crisp lines for lettering, striping, and two-tone paint separation.
