3M 7000045440 Steel Gray Masking Paper 6in X 1000ft

Product Description

The 3M 7000045440 is a steel gray masking paper designed for professional paint masking applications in automotive, marine, RV, and truck refinishing work. Built to be strong, flexible, and pliable, it holds up against sealers, solvents, basecoats, and clear coat systems without bleeding or breaking down during the spray process. Each roll measures 6 inches wide and 1000 feet long, providing substantial coverage for production-level or high-volume paint work. Body technicians and fleet painters rely on this type of masking paper to protect trim, glass, and body panels during prep and spray operations.

This masking paper is suited for use in professional body shops, marine refinishing facilities, and RV or commercial truck paint environments. Its resistance to common automotive and industrial coating chemistries makes it a reliable choice for both waterborne and solvent-based paint systems. The roll format integrates with standard masking machines for fast, efficient application along body lines, door jambs, and large panel sections.

Installation Notes

Applied by body shop technicians and professional painters using standard masking paper dispensers or hand-held masking machines. Ensure all surfaces to be masked are clean and dry before application to achieve a secure tape-and-paper seal. Remove masking paper promptly after the coating has flashed or cured per the paint manufacturer's guidelines to avoid edge lifting or coating damage.
