Silver is the base color of choice for shooting candy over and since seeing Dean Arnold's Thunderflite '61 T-bird, I wonder how that would go as a base for a candy metalflake paint job.
I think the Eldo roofs were brushed stainless, not chrome. I recommend practicing on a DeLaurean first ;-)
Candy flake might be a bit much and overpower the base effect. I know that Also does offer a kit to tint the chrome effect any color you like. I'm not a painter, just going by what I've read before.
I don't plan on making a stainless roof for my '58 Biscayne, merely thinking about having a reasonable facsimile perhaps. Still working on the "Mr. Fusion" propulsion system...
