I have sprayed this metal planter box innumerable times with the exact solution that the manufacturer suggests to accomplish rusting. After three days of spraying ad nauseam, it still looks nothing like the "finished" product. It's sturdy and arrived quickly, but, in terms of aesthetics and the time and dedication it takes to achieve the desired look, I'd say you're better off spending money elsewhere. Oh, and it's worth mentioning that getting your hands on multiple bottles of hydrogen peroxide during a pandemic is no easy feat!
