3M™ 6512 Masking Paper is a 2.6 mil steel gray roll engineered for high-demand industrial masking applications. Its lint-free, fiber-free construction minimizes surface contamination during paint and coating operations, making it a reliable choice where cleanliness and coverage consistency matter.

The paper resists penetration from solvents, lacquers, paints, and enamels, and withstands temperatures up to 400°F for one hour — supporting bake and cure cycles in automotive refinishing, aerospace component finishing, and industrial manufacturing environments. Its flexible, pliable structure conforms readily to contoured and irregular surfaces.

Each roll measures 12 inches wide by 1,000 feet long and weighs approximately 11.32 lbs, providing extended coverage per pack. Sold as a single roll and parcel-friendly for efficient restocking.
