Do you know of a product that can restore shine to powder-coated enamel cookware?

Guys, I fucked up. I have what was a beautiful two-tone colander that looked nice and retro, with a shiny red finish. After some use, there was a very tiny amount of rust showing in places around the rim, and my dumbass self decided to soak it in CLR like I do with anything metal that gets signs of rust. It didn’t occur to me that it would remove the gloss finish from the powder-coated enamel.

Now it looks and feels awful, like it has a dull, pink, rubbery coating instead of the beautiful glossy bright red finish of yore.

Is there a product I can use to polish it back to beauty? It wasn’t cheap and has been discontinued, so I’d like to restore it if possible.

I’ve searched online but my Google-fu isn’t worthy, apparently. Thanks in advance!

I would not be using this for cooking
- Why not?
  
  because possibly a thermal coating was removed and there is paint underneath which is coming off or reacting to things that are coming into contact with it
  
  also do you want to use it for cooking or look at it shine? It's a colander, not a bronze chandelier from Napoleon's castle.
Rubbing compound? Obviously wash it thoroughly but standard polishing methods for powder coated surfaces should work.
- Oh, like the kind for cars?
  
  That’s a great idea, thanks! If it works, I can send it through the dishwasher a dozen times and it should be fine, right? It’s the outer coating and I don’t plan to lick it much.
  
  Thanks for the suggestion!
  
  Don't forget this is for food usage. Make sure it is compatible.
  
  If it’s already showing signs of rust, I would think twice about putting it through the dishwasher
Google around for restoration services, I'm in south America so I'm no use to you but my sister had a couple of grandma's pots restored. They basically sand blast them and re powder coat them
Good luck on your journey. I don't have anything contructive to say to help, but this is certainly a way in which I would fuck up and I hope you find an answer.
You could try to polish it.
- I second this, if it's really a hard a material. From the word enamel I assumed a sort of ceramic coating, but the word 'rubbery' gives me a little hesitation.
  
  Anyway, a hard coating could be polished back to a shine with 3M polishing paper. The product I'm thinking of comes in a pack with 6 sheets, each a different grit, and they get fine enough that you could restore scratched and cloudy glass to clear.
  
  The product description said ‘powder-coated enameled finish’, and I had thought ‘enameled’ may have referred to the outer layer I destroyed. So now I’m just dealing with the powder coating.
  
  I think I’ll try your recommendation first – it’s the most food-safe and makes the most sense to me. Kinda worried I’ve irreparably ruined it without re-coating and re-firing it. I hope that’s not the case, and the ‘enameled’ part referred to the white inner bit which didn’t dull in the soak.
  
  e: maybe someone who knows more about these terms than me will chime in? I know a little about them because my grandmother taught ceramics and my father is in aviation where they do powder coatings, but not enough, obviously.
- I’m hoping to, thanks! I’m not sure what to polish it with, though, especially because it would have to be food-safe…
  
  Carnauba wax is food-safe, but non-abrasive, so it won't smooth the now-etched matte surface, and it's fairly soft, so not very durable. Many car waxes are based on it.

  I’d start with a little area to see how it turns out.
I wonder if a silicone oil could get some shine back as a last resort
You could spray it with clearcoat. No idea how that reacts to heat though.
