This is pretty basic chemistry. The strength of the acid and the concentrate of it are what make the difference. The same acids that are taking off the rust can be used to etch just takes a while. Other ones to play with are vinegar,wostershire sauce,ketchup,urine. As long as the mix stays away from oxygen it will work. Another thing that is a good idea after a acid wash is done is to soak the metal in a oil. Olive oil is a good one to let it soak in for a few weeks and then clean it and wax it.
