I'm in building something and I'd like it to have silver molding around it, but I'm making it out of 1/2" MDF and no one makes 1/2" Silver T-molding. I'm thinking of stuff that looks like this:

Or, more of a brushed look. I have an image in my head of this stuff, that's silver, and looks...brushed I think. Is brushed silver the really shiney stuff or the real dull worn looking stuff. That's what I'm thinking of is the dull stuff.
Any idea where I could find those?
Thanks
