In September, a Pipe Gate going into my Ranch was screeching at the homemade hinges. I sprayed it and the Padlock that locks it. We've had a wet winter and snow. I haven't done anything else to them, and they work smooth, and with no rust or noticeable friction on the hinge area. I have other Padlocks that I sprayed at the same, time and they work perfect with all the rain we've had. I've used the same thing on all my guns, and they work fine. A lot of things will work if used often enough, but I've never found anything that will compare to Eezox. Try a little on hinges or something that rub together all the time and see what you think?
