On our last Tt, I used Krylon Fusion spray paint to touch up stuff like that. I'm truly amazed at how well it stood up and it looked like it came that way. I even painted the plastic trim around the windows in the doors and put it on thick to fill cracks (normally a bad idea) and they looked good as new until I sold it.
X10!
OP: Get a can of Krylon Fusion and spray that new vent as soon as possible. It will 'never' yellow!
I did my stove vent, door trim, screen door bottom and fridge vent, and coach side mirrors with that paint. Looks like brand new and never yellows.
