do you put these stickers on the outside or inside of the window?

Outside, in at least 50*F weather.

i put mine on in 30* weather this fall and they have been fine.

i see, 27 degree weather isn't quite 50 darn

the warmer it is, the better chance you will have it sticking long term

ah, maybe i can get it in the garage with the heater if the kitchen isn't in the way.

Turn the heater on at idle for about 30 minutes (on max) and use a blow dryer to preheat the glass slowly from the outside.

I figured that were true, but I also figured if it were above 40 degrees it'd be ok. I put mine on in around 45 degree weather.

That explains why removing the 'defective' bonneville club sticker was so easy with the power washer. One spray, and there went bonneville club across the driveway lol.

heat them up again with a blow dryer or something and press them on again. hopefully not to much dust and salt have got behind the decal in the places were the adhesive didn't stick.

Also Don't do it when windy. I tried putting my 2nd one on and a gust came and fubared it up.
