Haven't done the badges as yet, as i'm deciding whether to remove them or black them. If i go down the black them path i'll do the same as Ghost HTX mentions which is to use Plasti Dip. I've used it before on my wife's 86, great stuff, just need to make sure you cover everything to minimise overspray, especially if you do it outdoors.
A hot tip when using Plasti Dip, use a toothpick when removing the plasti dip from the areas that can't be covered by tape (eg in between the lettering) as it lessens the chances of damaging the paint work
