Ok, here's a question for all you pros out there. I'm trying to detail and restore my bike, a 99 shadow ace. The previous owner probably never detailed it. I was able to polish the edges of the cooling fins, but now I'm noticing that the black painted portion is either dulled and/or corroded. Has anyone been able to polish this and restore the black, or has anyone painted this back to black? Even with the polished edges, the contrast isn't as good as it could be. I'd like to get it back to black. Thanks for any info!
