I'm looking to make a piece of custom trim for my "three piece" hood top. I want to finish the chrome trim back, from the radiator trim piece, but since it's not the normal folding four piece hood, it's going to require it be custom made.

I was thinking about purchasing a 36" piece of "half round" or "half oval" stainless bar stock and shaping it to look like the 32 radiator trim profile. How hard is it to file down the stainless, and then polish it. I will need to thread it, to bolt it to the hood from the underside (don't want to use double sided tape). Which "grade number" of stainless is soft enough to work with, and still give a good shine after it's polished?

Maybe it would be easier to use brass and have it chromed?

Looking for some advice, and ideas. Maybe even a source for this specialty metal shapes in So. Cal.

Thanks, John
