I used Eezox when I lived in a dry climate, and it worked just great, but when I moved to the coast, if failed rapidly, so I switched to better products. In my informal test of rust preventatives (bare metal left in the rain for a month with 4 different products in marked squares), Eezox failed at the same rate as bare metal. Breakfree was right behind it. The best of the four was RustGuardit, but it leaves a heavy, waxy film.
I'm now using Bull Frog, and haven't had a rust issue since changing over to it, but I'm pretty careful about taking care of my guns, too.
