I have seen several post on different threads about WD-40, what it is good for and not good for. In the early 70's, I learned to carry a small can of it in my tackle box. No matter what you are using for bait, if there are not biting........spay a LITTLE..... WD-40 on lure or bait. I kept this secret for many years. It has never failed. Good survival tip. For many years my friends couldn't figure how I always caught fish.
