No! Truten A606™, or Weathering Steel, will NOT rust through your panels.
You don't have to worry about your steel panels rusting all the way through with the Weathering Steel finish. This is because once the top coat of copper, phosphorus, and silicon is gone, the steel ionizes. This means the steel will not continue to rust.
Truten A606™ is designed to last just as long as other finishes, including painted finishes.
