Miniature paint roller?

I need a production tool for priming/undercoating my narrow, curved fan frames.

I’ve been using soft sable brushes with acrylics up to now, but with the cross-section of the frame typically 5/8" x 3/8", it’s pretty fiddly work, and requires a fair amount of time in smoothing down, to get a base for a ‘rub on’ gold top layer.

I’ve thought about a small spray set up, but have no real experience of it, and mainly concerned about over-spray in a small workspace.
Ditto, using foam or mohair brushes/pads, which I believe might give me a smoother coat.

I’ve also just thought of a miniature paint roller, having used full sized ones on walls, wondered if a roller about 1" wide and diameter might work.
Google so far has not produced a functioning one(only doll’s house models), so I thought what better place to seek advice than here.
Anyone tried and succeeded with this approach ?

Amazing !
You’ve turned the problem on its head, my favourite viewing angle. Must do more research.
Thanks.

If you search Amazon for brayer you’ll find all kinds of small ones in hard rubber or foam. I think they go as small as 2” wide or smaller.

For rollers, you can usually find at Lowe’s & Home Depot 1" wide rollers meant for “touch ups”. Much, much cheaper option than the machines set up for applying edge paint on leather (was pricing those recently as i do edge paint on my leather goods sometimes). Sticking with wool daubers for now (and maybe another option for your need–I found a huge lot of them on eBay, made by Tandy Co.–come in about 1/2" and 1" sizes–should be able to find at Tandy stores or any site or store with leather making supplies).

Thanks everyone.
Now fascinated by edge dying/painting from the leather workers, and ‘brayers’ for printing.
I’ll try not to get distracted from fans, otherwise SWMBO will have strong words to say !
Very tempted to try designing one that will coat all three faces at the same time !
