Okay, here's the thing. Maybe a clear coat on the metal would work. I've used it over the sink in my bathroom for soaps and lotions. Rusted after 2 weeks. Shame as I used to really like this little helper - I plan on sanding it down, applying an anti-rust clear coat to it and trying again, but for the money I honestly expected it to last a little longer. Maybe I'll just use the plastic instead :(
