3M 4737 Fine Line Tape is a blue vinyl masking tape with a natural rubber, pressure-sensitive adhesive that sticks reliably to curved and contoured surfaces. Its flexible backing conforms easily to complex shapes and resists lifting around corners or in recessed areas, ensuring sharp, clean paint lines. This tape is designed for high-temperature paint processes, withstanding bake cycles up to 300°F (149°C) for 30 minutes. It holds firmly and removes cleanly with minimal residue. For indoor use only; not recommended for outdoor exposure. Available in multiple versions to suit different needs: opaque blue (4737S), translucent blue (4737T), and linered versions (4737TL, 4737SL). Ideal for fascia, rocker panels, two-tone designs, and other multi-color automotive paint jobs. Custom die-cut alternatives are also available to meet your specific application requirements.
