Drew's first tape invention was a masking tape made for painters in 1923 (this tape was designed to help painters paint a straight border between two colors). This early masking tape was a wide paper tape with adhesive on only the edges of the tape - not in the middle. Drew made an improved tape called Scotch (TM) Brand Cellulose Tape in 1930. This tape was a clear, all-purpose adhesive tape that was soon adopted worldwide. The first tape dispenser with a built-in cutting edge was invented in 1932 by John A. Borden, another 3M employee.

The first aerosol can (a can than contains a propellant [a liquefied gas like flurocarbon] and has a spray nozzle) was invented in 1944 by Lyle David Goodloe and W.N. Sullivan. They were working for the U.S. Department of Agriculture and were trying to find a way to spray and kill malaria carrying mosquitos during World War II for the soldiers overseas. The "clog-free" spray valve was invented by Robert H. Abplanal in 1953.

The first spray paint was invented by Edward H. Seymour in 1949. Seymour's wife Bonnie had given him the idea of an aerosol applicator for paint. The first spray paint he developed was aluminum colored. Seymour formed the company, Seymour of Sycamore, Inc. of Chicago, USA, which is still in operation.
