Agree with saf. They are ugly, but unless you have something to replace it, you’ll get rained on and won’t have shade. I hated mine and swore I’d remove it as my first project. 4 years later, I’m happy it’s there (though still scheming for an awesome replacement when I have the time and money).
Go for it if you want, but I recommend a can of Rustoleum metal paint in a color you like better first.
