I just did my tailgate following some of the ideas above. I bought a set of decals from one of the vendors and then: - painted the center panel of the tailgate Arctic Beige (the letter color) - after several days, I applied the white decals to the letters - painted the tailgate and over the decals with body color (black)
I tried to peel off the decals shortly after painting but the adhesive was just too strong and I couldn't do it without messing up the black paint. I then waited about 5 hours when the black paint was half-cured and less prone to damage; I had to fight the adhesive but managed to get the decals off okay. I have a couple of small areas in the "O" I need to touch-up the line. I added a "handle" to each decal by putting a slit in it and then sliding a small piece of tape into it so I'd have something to grab; this was somewhat helpful. I think I had read somewhere that you should weaken the decal adhesive before applying them by pressing them against your denim jeans first; I don't remember where I read that but it now seems like good advice.
I'll try to post a few pictures. I'm using single stage Tamco paint.
