thumperfbcBest way to paint a chimney topper thing?
The little screen thing that sits atop a chimney blew off a couple months ago and I’d like to paint it before the chimney sweep puts it back up for me. It’s just a basic steel and somewhat rusty.
Is there a product I can use to paint over the mild rust with, or do I need to remove the rust first?
How hot do these get? Will any basic spray enamel work as a final coat, or is a high-temp paint needed?

AlyronYou can paint it first with a rust converter and then top that with Rustoleum or other paint meant for metal. Just wire brush any loose rust before you start.

Yep. Rust converter turns rust into black primer. Available in spray-on or brush-on.

That's a trip back in time, and memory of Loctite Extend! In my more fastidious days I used that on visible parts of brake rotors, purely for appearance.

pace40I did mine with high heat BBQ paint about six years ago. Still looks great.(oil burner flue) I did wire brush sand the surface beforehand though.

PASigI'd replace it with a stainless steel one, then you never have to worry about it again.

thumperfbcI could probably use a wire brush on a drill to clean it up first. I didn’t consider that.
Edit to add: just knocked off all the loose rust with a grinder and wire wheel, only took 10 minutes or so. Still a rusty red color so I’ll pick up a rust converter.
Then topcoat goes on that? I have some of the premium paint+primer spray from one of the big names… so I can use that or a bbq paint I suppose.
