I don't know what grill you have but we have the billet grill and it's attached with only a couple screws. We yanked it and painted it. Took only a hour. Looks 100x's better.
Careful if you use any products on your dash if you haven't used anything before. Many times a dash can crack in the sun if you've never used any type of 'armor all' type product in the past.
For our paint we use Prima showcar wax and polishes.
Oh yeah and off road trucks don't get tire dressing!!!!!!!!!
That's just wrong!
