What to use on door window trim?

[Beelzebot]

Have a 2005 Civic, and the coating on the metal window trim is faded.
Originally it had what seemed to be a thin, rubber-type coating.
The car is kept outside, which contributed to the fading and spotting of the original pieces.
I`ve tried everything else, polishes, waxes, even Meguiar`s Ultimate Black Plastic Restorer, to no avail.
Somewhere I`ve seen where a detailer sprayed these trim pieces with Plasti-dip.
I plan to remove these trim pieces before spraying them, but what is best to use for longevity?

Ignore the roof trim piece in the pic below.

Its gonna last as long as the quality of your prep and paint. I think plastidip says 2-5 years max.

I`d use Rust-Oleum satin black enamel. It`s not car paint durable but as good as you will get in a can. If you regularly wax it, you should get at least 5 years.
