All the badges on the car desperately needed refreshing. So after asking for suggestions on various FaceBook Groups, and getting lot’s of advice, I settled on some Humbrol Model Paint.
The process was very tedious. For the “Shields”, I mainly used the pointy end of some wooden skewers to apply the paint and “push” it into the corners. If it was really small and tight, I’d use the tip of a syringe. Same, same for the DeVille badges. For the Statesman badges, I just used a very fine and small paintbrush.
This is the result.
