What is the recommended application method for metal roofs?

The recommended application method for Rust Bullet on Galvanized Corrugated Roof projects is an airless spray system with a 517 to 523 tip at an approximate 3000 PSI. Two or more coats should be applied depending on the desired dft (dry film thickness); each coat of Rust Bullet will add strength and durability to the metal roof. Please refer to our Application Guidelines for detailed instructions on airless spray systems.
