I'm actually telegraph collector, and am aware that bugs, at least, wern't wrinkle painted until 1940.

When was wrinkle paint first used?

I seem to remember early radio stuff may have had wrinkle paint earlier.

Wrinkle paint was extensively used throughout the radio manufacturing industry during the late 1920s.

Wrinkle paint performed a function similar to that of textured sheet metal in the 1980s appliance industry- it helped conceal cosmetic defects, leading to a lower inspection-rejection rate and increased profits. Early sets were highly finished inside and out, even the pressed steel chassis... and wrinkle paint was effective at hiding handling scuffs and dings which would have been unsightly if the part had been painted with smooth enamel. This paint fell out of favor sometime in the early 1930s, when people lost interest in admiring the innards of radios. A few manufacturers continued to use it (Stromberg-Carlson comes to mind) but most abandoned it.

Years ago I had a "Neutrodyne" (both a brand name and a circuit type) radio, circa 1928, which was built on a massive shallow pan-type chassis similar to that used by Atwater Kent... and every part on it, including the chassis itself, was painted with brown wrinkle paint. It was truly a behemoth.

It was in pretty extensive use by 1926 and was at its peak around 1928-29.

Thanks for the info!

Interesting how the major telegraph manufacturer ("Vibroplex") stopped japanning their bugs in 1940 and switched over to wrinkle paint when the radio manufacturers were phasing it out

I always thought Japanning was also a way to hide surface casting defects since the lacquer was so viscous. It was probably cheaper to use wrinkle paint rather than lacquer since when they lacquered their bugs before 1940, they also added decorative gold pinstriping which was done by hand.
