Etch primer... (what is this?...)
Spraypaint...
Etch primer is a primer/basecoat which has an acid in it, so that it "eats" into the surface and sticks better. FWIW I recently restored an old steering wheel, this is what I did, which might help.
Give the metal a light sanding. This is mainly when you have existing paint you want to paint over, but it will help the etch primer stick better anyway.

Apply your etch primer in light coats to make sure you get a nice, even surface. Eg to get to this point it was 4 light coats of primer, and don't aim to get full coverage on the first 2 coats, you shouldn't get full paint coverage until after the 3rd coat. Be patient and apply light, misting coats. The primer dries fast and you can recoat after 10mins so this isn't too much of a hassle.

Then for your application I'd recommend this stuff, VHT epoxy paint for rollbars.

Again, be patient, apply light coats and aim to do the job over 5-6 coats.

It'll dry to a slightly mottled, textured satin finish like so.
