By grill mod, do you mean painting the oval ring? If you do, I hope you sand the [censored] out that to get the chrome off, becuz if you dont, you will have chipping like no other within the first month of the painted oval.

The best way to do this tho, is to soak the ring in muratic acid for 2-3 weeks, yea it takes a while, but it works the best at getting the chrome off. Or, just get some sand paper, sit infront of the TV, and go to town.
