A protective tape covers the adhesive on the second tape. The assembly is mounted on one of two portions of a surface to be painted with the first edges aligned on the border between the portions, paint is applied to the other portion extending also over the aligned first edges; the protective tape removed and the second tape pivoted into adhesion with the other portion.
