The samples shown were first assembled in wall and roof mount configurations, with their brackets "threaded" onto the ductwork.(Optionally, for contrasting colours between the ducts and brackets, you might paint the parts separately, then assemble)
We spray painted the completed HVAC duct assembly with a "Cast Iron Gray". You could use any gray for an oxidized / galvanized look, or a silver for a "new" look.
Then we washed on a watered down "Vintage White" acrylic to represent oxidation.
Once dry, we spot-washed on watered down "Burnt Orange" and "Burnt Umber" to create rust streaking and stains.
You can also use weathering powders with great results
