From Cold War rocket labs to flooded pickup trucks, and from jungle war zones to guitar shops, this little blue-and-yellow can has had quite the journey.And that journey began in a little lab in California … with just three employees. But they managed to create the perfect product for NASA without knowing it would morph into a household name.You’ll hear how:* A self-taught chemist named Norman Larsen failed 39 times before creating the 40th formula that changed everything* The first users of WD-40 were rocket engineers who smuggled it home in their lunchboxes* A hurricane, a jungle war, and a cow ointment all helped make WD-40 a household name* The company survived fallouts, rivalries, and resisted every urge to diversify — by sticking to one can, one mission* And why, to this day, the exact formula is locked in a literal vault. 🔒🔍 What’s Else is Inside This Episode (and details you’ll read in the newsletter):* 🚀 The Space Race’s unexpected effect on anti-rust innovation* 🧪 The magic of Water Displacement #40* 🔧 How WD-40 went from toolboxes to trenches (yes, even Vietnam!)* 💼 The marketing masterstroke of not marketing* 🌪️ The hurricane that made it go viral — before viral was even a thing* 🐄 The cow udder cream side hustle you didn’t see coming💡 Key Takeaways:* Persistence wins.
