factory console. Cast aluminum? Powder Coat?

Hey guys, well I just got my 67-69 factory console today that I bought off of good old ebay. I had no idea these were cast aluminum. I picked the box up and was very surprised at the wieght.
So my question is, has anyone powder coated one of these?
I am considering blasting it and powdering it, but I know that all metals have residual stresses in them and I obviously dont want it to warp. So any body tried this?
Also I was going to make a new top plate out of some very cool corugated stainless steel sheet that I have, but again the top plate (chrome / argent) is metal also. I think it may hold its shape with out any problems because of its complex shape. So I may just powder coat that to make it fresh looking.

Gimme' some feed back guys thx :headbang:
