Do you love big bluegill?
I'm one of those who thinks NOT. Supposedly it had fish oil in it long ago (unverified), but not now.
It is nothing but petroleum based chemicals, oil and propellent.
But people still swear by its fish catching attributes, and everyone has a story about it..
So are you one of the WD-40 devotees or a skeptic?
I've heard about this as well, along with that it catches fish. But I'd rather not put that stuff in the water i'm fishing.
The only thing I can think of is because that it's scented, catfish will try to eat whatever it's sprayed on, because I've heard of people just using straight up chunks of bar soap to catch catfish as well. It's probably that and the people haven't tried using cut bait haha.
