I just repainted my black trim around my headlights and it turned out great.  I used a glass paint made by Delta that doesn't require baking.  It isn't as smooth as say a spray paint would have been (you have to brush it on) but I'll sacrifice the smooth surface for something that is going to stick around for awhile.  I ended up brushing two coats on so it was think enough to cover the glass without streaks.  This stuff looks like it's not going anywhere for some time.  Just wanted to share this with the group.
