Metal, regardless of how well protected is a “living finish”. Meaning that you may notice slow changes over time, even though the metal is protected with a clearcoat. They are indeed alive, and become more beautiful and interesting with age.
Our “Verdi” and “Iron Rust” finishes are more alive than the others. We specifically hurry the natural aging process on these finishes rather than asking you to wait years for the natural aged patina look to develop. Even our high quality clearcoats won’t completely halt the aging process. The result is that you may notice some staining to your mounting surface or below the sign.
