Bare and painted metal is slick and prone to rust, so the primer has to both bond and, ideally, resist corrosion. Here are the primers that grip metal reliably โ with the honest downsides of each.

- Fast 1-hour recoat
- Budget-friendly bonder with water cleanup
Cons
- Lower coverage per gallon (~300 sq ft) than wall primers

Frequently Asked Questions
- What primer sticks to metal without peeling?
- A bonding primer such as KILZ Adhesion or Zinsser Smart Prime is formulated to grip slick metal. For rusty metal, remove loose rust first and consider a dedicated rust-preventive coating.
- Do I need a special primer for rusty metal?
- Yes โ for active rust, a rust-converting or rust-preventive primer/paint is better than a general bonding primer. Sand off flaking rust first for any product to adhere.
