Do you need to prime rusted galvanized metal?

Yes, it is advisable to prime rusted galvanized metal before painting. The primer helps to create a better bond between the rusted surface and the paint, preventing peeling and ensuring a more durable finish. Use a rust-inhibiting primer specifically designed for metal surfaces to effectively seal the rust and enhance adhesion. Proper surface preparation, including cleaning and removing loose rust, is also essential for optimal results.
