Valspar Direct-To-Metal Semi-gloss Neutral Interior Water-based Industrial Enamel Paint ( 1-gallon )
Can this be used on galvanized metal duct work for HVAC? If so does it need a primer first?

For Galvanized Meta we suggest this surface preparation. Allow the galvanized metal duct to weather for 6 months and solvent clean per SSPC-SP1. If weathering is not possible or surface has been treated with chromates or silicates, solvent clean per SSPCSP1 and apply a test area. Test adhesion after one week dry time. If adhesion is poor, brush blast per SSPC-SP16. If you have any other questions, please let us know.
