i wouldnt be afraid of using the oil or WD-40 sure it stinks at first but i have never had problems. use a rag and spoary it onto the rag and wipe down parts could rust. rub it in good and let it hang for a day. i do this at the end of every hunting season to prevent from rust and i still get deer under my stand. if you are still afraid of that, after you do it, spray it down with a little bit of white lighting scent eliminator. that stuff takes the smell of gas off hands.
