Primer or sealer

[mjgord5113]

Howdy folks. It's been a while since I've last posted anything.
My question is about what's good/better for covering metal work? Some ideas I've came across is - Rust encapsulator, converter, reformer,inhibitor or Epoxy Primer?

Epoxy primer is always better when covering bare metal.
