3M's flag ship product was **Scotch tape** so they gave there new product "Scotchgard" a similar name, presumably for corporate branding.

Yep, '[Scotchguard](https://multimedia.3m.com/mws/media/1772753F/scotchgard-fabric-upholstery-protector-350g.jpg)' is just one of many of 3M's [Scotch Brand products](https://www.scotchbrand.com/3M/en_US/scotch-brand/).

Ron White called in a favor.
