i believe under that gel on the blue oval is a chrome surface 
iv done it to my F-150 Supercrew, iv also acetoned my F-150 badges & made them chrome.
ill try to post some pics as a sample. i just wanted to know if it could be done w/ the Focus.
I've seen a website where the person changed the color on their Ford emblems... if my memory serves me, it was on an F150 actually. I dont' see why you couldn't do the same to the Focus Ford ovals, I'd think they're exactly the same. Just saw on eBay the other night a Ford oval in yellow, so I'd try it the way you did your F150, see how it goes!
