All I did was go to homedepo and picked up a 6 dollar can of Plasti Dip. Its a spray on rubber coating. Make sure you buy the spray in a spray paint can instead of the "Dip" that comes in a regular paint can. Then just take some rubbing alcohol on a cotton ball and just clean the surface really good. Then take newspaper and mask of a square around your emblem (you dont need to mask but it saves you alot of work). Then spray coats on one at a time. I did about 5. Make sure each layer you spray is thin to get the best results. Its better to have a lot of thin coats then a couple of thick sloppy ones. After letting each coat dry for about 15 to 20 mins. you can take your masking off and just peel the extra plasti dip off. Peel in slowly and it will cut its self out around the letters. The best part is if it looks like crap peel it off and start over Its pretty amazing stuff. If you have some splatter on your truck just take a microfiber cloth and rub it real good and it will come off. I am going to do my grill today if I have time.
here is a youtube link of some one doing it:
