Anything that is plastic that tries to look like metal looks cheap. And let's be honest, T-molding looks cheap enough already even though us nerds like it.
Says the guy who uses X-arcade joysticks.

I don't agree with your cheap looking statement. I think T-molding makes your project look finished, professional, and can help tie the colour scheme together all-around. Just look at projects that don't have t-molding...they look unfinished, boring, and doesn't accentuate the curves of the cabinet making it feel drab or mundane.
Like I said, mostly chrome is used for casino games. But I've used chrome molding on one of my cabinets, and it turned out pretty nice, gives the cabinet a decadent look and though I could have gone with a solid Yellow, or Orange, Chrome is neutral and will go with any colour combination.


And for a retro-futuristic cabinet that Danny's putting together, chrome is an obvious choice. Barring that he can find 5/8"...which I fear is going to be tough.
I'm still sticking with my white recommendation but yes chrome will work fine. It's just as "bendy" as the others .
One thing to be careful about with chrome though is that unlike white and black and the others, it's not a solid color molding. its actually sorta clear with a sort of mylar coating over it.
the few times I've used it (from t-molding.com) it came with a protective coating over it that you remove after finishing. But I've never had an issue with it.
mgb is spot on. The chrome is coated, but it's durable. I too haven't had any issues with it, even with getting banged up a bit. And yeah, it bends just like any other t-molding.
Hopefully it's available in 5/8" somewhere, though I cannot remember seeing them listed at that size.
