3M3434 Masking Tape - 25mm x 50m - Blue. The best available tape for critical line initial masking. Will not lift despite repeated baking, and leaves no residue on paint, glass, plastics or rubber. Supplied on 50 metre rolls. Equally effective on solvent or water-based paint systems - for which its rubber-derived adhesive was specifically developed for exceptional water resistance.
