3M 6303 Scotch Fine Line Tape 218 is a precision masking tape designed for multi color striping, custom graphics, and detailed refinishing work. Its ultra thin polypropylene film provides crisp, sharp color separation lines with minimal paint buildup. The tape conforms easily to curves and contours while maintaining edge integrity for accurate layouts. Resistant to solvents, moisture, and heat, it performs reliably in bake cycles up to 250F for 30 minutes. It also removes cleanly without residue, even when applied over fresh paint. The special processed backing allows taping over freshly painted acrylic lacquer or enamel surfaces sooner, supporting efficient workflow in professional refinishing environments.
