+1 for SockMonkey!!! He is the man when it comes to these decals/stickers/vinyl's. I got them installed today and it was as easy as following the included instructions. Turned out good and I think it looks good on there with the Desert Sand truck color. The grill is drying right now as well, painted matte black with Aluma-Hyde II epoxy paint. After a couple of weeks when good and dry the grill paint will take wax just fine and theat just makes it look even better and helps protect the paint.
Here is a link to some instructional videos on applying these, below the video are thumb links to other applying videos.
