I worry that spraying it liberally on the chain it might seep past the O rings and thin the grease in the rollers. Afterwards I spray on Dupont Chain Saver and wipe off the excess. This has proven to work very well on all my chain drive bikes. The Dupont product does not collect grit and does not fling off on the rear wheel. When I used conventional chain lubes years ago, my chains often were binding and needing replacement in as little as 6000 miles.
That's one of those internet legends that's been kicking around for years. A guy decided to test it and soaked a new oring chain in a bucket of WS for a few days. When he disassembled a few links there was so sign of WD past the seals.
But as my Grandma always said: "Never let the facts stand in the way of a good story."
