I just bought some used trolling gear that needs a little tlc. Some of the roller guides need some lubrication and I mentioned to the seller that I would hit them with some WD-40. He said NOT to use that oil on any fishing gear. He went on to tell me that its scent has an adverse effect on attracting fish AND there was a list of several things that shared this effect including human urine! Does anyone else know about a list of things we should not come in contact with while fishing??
