Need help with WS6 Emblem
Go to your local auto store and pick up some double-sided 3M emblem tape. Get the thinnest kind you can. Cut the tape into very precise pieces to put onto the back of the emblem after you clean off all the old adhesive. Take the backing off of one side and stick the tape to the emblem, but leave the second backing on (the side that will go on the car). Then make sure all the adhesive and tape is off the spot on your car where it is going to go. Use some rubbing alcohol on some cotton pads to clean the area. Let dry for a couple minutes, then peel off the backing on the tape which you've put on the emblems. Stick them on, maybe run a hairdryer over them as you press firmly to make sure they adhere well. Then you're good to go. 
That should be all you'll need to do. As long as the surface is clean and you get it to adhere right, you shouldn't have to worry about it coming back off for as long as you'll own the car.
