Blo??? who works at Lockheed corporation. I seem to remember her posting a note saying that WD40 was developed by Lockheed during WW2 as a "Windscreen De-icer" and formula #40 was the successful one. Back me up Sharon if you are still out there:-) Tony Flynn Grandad. Retired at the beach. Bay of Plenty. New Zealand
