In fall 2016, the National Park Service undertook the restoration and painting of the Rodney Cannons at Fort McHenry. These cannons were cleaned back to bare metal via a high pressure water jetting process and received a robust Acrymax coating system designed for corrosion control and color retention.

The primer of the system was PC-125 Rust Inhibitive Direct-to-Metal primer, the intermediate coat was PC-535 Rust Inhibitive DTM Elastomeric Coating, and then system was finished with two coat of AF-4400 Field Applied Fluoropolymer Coating.

Check out pictures of the project taken a year after install – the finish still looks excellent and will for years to come.
