This is a very cute planter. Unfortunately the bottom rail of the grid shelf was obviously painted over rusty metal, and the paint is failing. This image is one section of it, a good portion of the bottom rail is losing paint with rusted metal underneath. 
The manufacture has been kind enough to respond to my complaint, but no longer has product to replace it with. I expect Wayfair will refund me for this outdoor product that will obviously fail unless the entire bottom rail is sanded down to clean bare metal, primed, and repainted.
