What is galvanized metal made of?

The protective coating around galvanized metal (usually made of zinc) can corrode with exposure to heavy rain or an accidental splash of a powerful household chemical like muriatic acid. With continued exposure to the atmosphere, the metal piece can form white rust. While you should still scrape off loose rust and clean the metal as recommended above for other metals, you should only apply a latex all-surface primer or universal bonding primer ($5 to $13 per 12 ounces from brands like Rust-Oleum via Lowe’s) and a latex interior-exterior paint ($11 to $13 per 12 ounces from brands like Krylon via Walmart) to galvanized metal.

Filling the pits with an auto body filler product (like Bondo, available from Amazon) would be your best option for restoring it, or else you’ll need to replace the metal piece altogether.
