Many years back I attended a sponsored program where the fisherman trolled underwater cameras filming saltwater salmon strikes and takes with all manner of lures, baits, and scents including WD 40. His best scent was bilge water which was a mix of all the fuel, oils, battery acid, and drinks that had dropped or leaked to the bottom of his boat.
One revelation for me was that for every take or hookup there had been about 20+ fish that had made an attempt or two and missed. One could troll for 1/2 hour thinking there were no fish about before having a successful hookup.
My take is that WD 40 probably won't harm one's chances.
