I am making some wind chimes out of old bottles, is there a mirror paint that can be used and painted on the OUTSIDE OF THE BOTTLE, not the inside? Can not be the inside because the dinger will be hitting the inside and will chip the paint. I am aware of the silver and gold paint that Rust-oleum has that you spray on what, in my use, would be the inside of the bottle to get a mirror effect on the outside. Have looked locally but can not find anything. Thanks for the help.
