Well I actually sanded mine smooth and primed and repainted it. I used a silver metal paint and it looked show ready . Someone was making new alum bases at one time but I have not seen them in person. You may also want to check with GCar if you want to replate yours .
I'm looking at the Valspar silver brushed nickel 66005 spray can... might be my only option. Do you recall what you used?
