Cleaning a Galvanized Duct

I want to clean and coat a galvanized duct at the plant. What type of coating, besides painting, could be applied?

To clean the duct you should follow the NADCA Standard ACR 2002. There are different products you can use inside the ductwork, if the ductwork is crawlable you may use a paint_sprayer_airless if not you can use a robotic car to introduce the application tip inside the ductwork.
