What can you do to protect powder-coated steel patio furniture from rusting?

We bought patio furniture a while back, and it's made of all aluminum, which is great bc after several years, there's not a spot of rust. We love it. We got the gazebo that went w/it, but it was bamboo, and after several rainy/humid summers, it disintegrated.


Now, we found another gazebo that matches our chairs, but it's made from ';powder-coated rust-resistant steel.'; We know this stuff will likely still rust, even though it's ';resistant'; to it, because we've seen it happen w/neighbor's/family's stuff etc.





Is there anything you can do to it to prevent it from rusting? We hate to spend the $ on something that's going to rust out in 2-3 years.





Any opinions of that Rustoleum stuff? My inlaws used it but their patio furniture still rusted apart. I don't know what to do. Is there some kind of oil protectant or something to rub on it periodically? Any experience with powder-coated steel patio furniture?





Any ideas would be great, thanks!What can you do to protect powder-coated steel patio furniture from rusting?
apply RustSeal a non porous rust preventive coating, a popular product used by auto restorers but stops rust anywhere.What can you do to protect powder-coated steel patio furniture from rusting?
i don't know if this will help,but if you can get hold of Plastikote clear spray,it will put a durable long lasting layer of colourless plastic over the aluminium.this should in theory preserve the metal for longer.if you can get hold of it,ask the shop staff first if it's suitable although I'm pretty sure it is.
