I recently did mine and my wife's. They came out pretty decent except where on my front emblem I let the drillbit get a little wild and made a small notch in the inside chrome ring.
Once you get them off you'll have to drill out the plastic tabs/rivets on the back side of the badge and just slowly take it apart. Paint to your liking and super glue back together.
Hers in some shade of pink with metallic black letters. Pained me to do this on a lifted truck but since she got the "hand me down"...... 20151103_142220 by Dustin, on Flickr 20151103_141713 by Dustin, on Flickr
They didn't come out perfect but I'm pretty happy with them. Unfortunately I didn't take any pics of them apart.
