3M 233+ Green AUTO Masking Tape, 1-1/2in x 4 Roll – Clean Edge, Paint Masking

Product overview

The 3M 233+ Green AUTO Masking Tape is designed for precise masking in auto body work and related paint tasks. Its distinctive green backing provides soft, highly conformable support that hugs curves while preserving crisp lines and clean edges along complex surfaces.

The adhesive is formulated to grip a wide range of substrates, including EPDM, and removes cleanly within a practical masking window of up to five days. This balance of adhesion and easy removal helps keep surfaces intact while delivering dependable masking performance.

Users will notice strong resistance to paint bleed-through and a heat tolerance that accommodates short exposures up to 250ºF (121ºC). These characteristics contribute to more predictable results in typical workshop environments and during quick-curing processes.

Manufacturing takes place in an ISO 9002 registered facility, underscoring a commitment to consistent quality across production batches and global standards.
