I have a parrot pen that has a bit of rust on the bottom part, the legs and slide out tray. I don't wanna throw it out a moment ago cause I was rash in storing it. I sanded the nouns with the rust and it looks ok and it still strong and what not after all it is wrought iron but I a moment ago wanna coat it so it looks a little better and it isn't exposed if my bird is out hopping on the floor near the nouns. The cage is black vein contained by color but I'd be willing to change the color of a moment ago that bottom part if I had to.

I did read that any non-toxic latex based paint is undamaging for use on bird cages, but I would check against Eartheasy specifications
