As for applying the big sticker, I used windex. I sprayed it lightly on the sticker and even lighter on the hard lid. Then lined it up and applied it. Let it sit until dry and then remove the covering off the letters. Have rag in hand to wipe any excess windex away.
Expanda, I really think its a great size and stands out. I guess my van has a few odd stickers to stand out from the rest. Would've put one on the front as well, but.......
I'm really happy with it.
Cheers again Dion.
