65 Grill Steel or Aluminum

[kizer]

I was tinkering around in the garage today waiting for the wife to come home so we could eat lunch together. I lightly scuffed my grill that was painted white by only lord knows who. Anyways scuff*scuff I see metal. I mean it was so light of a scuff with a rather fine sanding block it was insane.

Now is the grill Steel or Aluminum? I'm sure it might be a bit more obvious if I took it off to look at it and feel the weight of it, but I haven't got that far in my plans.

The reason I ask is if its Steel I'm guessing I have to paint it something or have it dipped. If its alluminum couldn't I just strip it down and run with it bare?

I really like the look of bare metal and I don't want to really run with Chrome so I thought if I could have a brushed look I'd be in hog heaven. I even thought it would be cool to strip down the bumpers and clear coat them or something. Hell I don't know I'm not a painter.
