Guys, this technique was designed to take a floating lure and turn it into a suspending lure, or a sinking lure, it's called drill & syringe? I did some research and talked to one of my crankbait buddies who has forgotten more about crankbait fishing than I'll probably ever know. LOL He said it was used by lots of tournament fisherman back in the 70's where he came from, the Carolina's. Pretty awesome when you think about it, you can adjust a plastic crankbait in a non permanent method, because you can take the water back out and reseal the hole and the lure is back to factory.
Anyway, sorry to anser my own question, but I thought some of you crankbait guys might want to hear the story.
Thanks have a great day!
