Thank's guys!
Emblems are "pre-foiled", then the red paint went on and the emblems where polished/scraped clean. I then used parts of the decals to get the colour right in the easiest way possible. Have tried painting them on earlier cars but thought this was worth a try. So what you see in the picture is actually four small pieces of foil and decals.
Did the same on both bonnet and trunk emblems, pre-foil and decals afterwards.
