The skinny on scent is this...The old gas thing might have actually helped you. Let me back up a little, get comfortable,this is gunna take a bit to explain. For whatever reason through selective breeding, grand design, or whatever you believe in salmoniods and in particular chinook have developed hyper smelling. I will stick with Chinook for this as they are the most critical and the rules for scent control apply to the rest of the spiecies.
Human scent... What constitutes human scent is kinda self explanitory. The oils from your skin, bacteria, and and possibly breath (sneeze or cough on your gear you might want to consider washing your rig). It seems that this problem is more male oriented than female. After several studies have proven that testosterone is the major contributing factor. Chinook have developed a fear response to it and the higher the level of testosterone in the fisherman (teenage boys, balding men) have a harder time catching chinook and and take appropriate action. Women on the other hand while having testosterone levele in lower amounts have a built in fish attractant estrogen. A chemical compound that makes up estrogen also operates as the breeding phermone in chinook. It explains why at times women out fish men handily. As far as out side sources, tobacco, 'tater chips, etc. may or may not put fish off, I personally avoid it. Bananna's are steeped in maritime history. In Hawaii they are considered bad luck and will literally get you put off a boat. Chinook have a love hate affair with potassium, 1 day out of 30 they love it, 29 they hate it, you guess which one. My personal opinion, I will not allow banannas in my house from about 2 weeks before the chinook show until after the run is over..my wife thinks it's silly but whatever. Chinook can also smell mono carbons in ionic chains. These often are excreated by schools of bait fish and are present in petrolium products. WD-40 has a large amounts of this however it will fail to bond and float off in water taking with it oils from human skin contact. Better for this is a floride free, light scented tooth paste that can be brushed on and rinsed off.
The mud, rocks, twigs thing is trying to use natural minerals that are inherant in the river system as a cover scent. It has it's pro's and con's, but nitrile gloves are still the way to go. when cureing eggs, herring, shrimp whatever you much better off NEVER TOUCHING BAIT WITH BARE HANDS. After they are cured they are only marginally better. I hope that answers some of your questions. I'm working on a piece of equipment that may actually render equipment "scent free" in about 10 mins of exposure, however have no difinitive way to prove it currently.
