Rust issues

What is the best way to deal with rust in my evaporative cooler pan. I scraped and wire brushed flaking paint and rust spots as much as I could but now all I'm left with is a lot of rusty patches and powder which I plan to vacume out but unsure what to do now before I spray coat it. Do I do more to remove the rust before I paint it?

Welcome to the forums Cynthia!
It's always best to remove all the rust but that isn't always feasible. What do you intend to spray it with?
