As an interim "fix", I did my F2 badges by first beadblasting them to remove the old anodising and paint, then I etch primed them, painted them with a rattle can of Dupli-color metallic gold, then brushed the black back with a fine artist's brush and flat black model paint, sprayed the whole thing with 2 pack clearcoat, and they look pretty cool.
I did buy new badges, but mine looked so good, I never bothered to replace them, however, when I repaint the tank that Tim Kasper sent me all the way from Texas (thanks mate!) I'll put the new ones on. Cheers, Terry.
