ok i got this off of a ford probe site but it should be very similar for the explorers
Here's how it's done.
1) Warm the Emblem with a hairdryer for about 2 minutes. Turn it over and carefully pry around the perimeter with a thin flat object. Now you'll have the front (painted) part (piece 1) and rear seal (piece 2) seperated. Set piece 2 aside where it won't get dirty, the adhesive on it is enough to reseal the finished emblem. CAUTION: if you don't warm the emblem enough before prying, you will crack the clear portion!
2) In order to change the color you must remove the stock color. On the front of piece 1 you'll notice the silver "FORD" is raised on a blue background. When you flip it over the "FORD" is inset and the background is raised. Take fine sandpaper (or a fine emery board) and carefully sand away the background color.
3) Now paint the backside of the emblem any color you want. Touch-up paint or Testors model paints and brush will work fine for this. Allow it to dry thoroughly.
4) Put the 2 pieces back together. And admire your work. If you broke off the mounting tabs removing your emblem, 3M auto adhesive tape works great.
You can also sand the front of the emblem with 400grit sandpaper and clearcoat it, if it has any minor imperfections.
