Well, never let facts get in the way of a good myth...
PTFE was invented by DuPont in 1932 - "Teflon" is just a trade name. So its discovery and development had nothing whatsoever to do with space.
Aerosol cans were patented in 1931 in Europe (Denmark?) so hardly new-fangled in 1953 when WD 40 was created as an industrial product so named from "water dispersant" product No. 40. Although it was developed for corrosion protection in military missiles it had nothing to do with NASA which would not be created for another 5 years.
"Septics" is unpleasant and probably racist, even with a smilie. Ugly.
