Hey sewer.
Yeah, I thought that too. I used windex but only on the ends of the sticker. After I mark where i want them, I spray the ends so you have some movement to get the alignment right and press them down. Then you can either squeege out the windex or towl dry it and use a hair dryer(no heat gun) to set the ends.

Also, if you get any airbubbles under the larger stickers, like the main ones on the 260, you can ***** a hole in them, spray the hole with windex and work the airbubbles out. The windex lets the air come out before the hole closes up and you'll never be able to tell the hole was there[8D]

Hope this helps and good luck.
Happy flyin'
