I got some decals from edecals.com and they were the no water kind. I don't know about the sunshades though. Mine I taped into position at the top and started peeling the backing off while squeegeeing it to make sure there are no bubbles etc. I think they look really cool. But yeah, there's really only two ways to do a decal. Shady told you the one way and the dry method is the other. Uh, did you get them from edecals.com or are they from an autoparts store? If they were from edecals.com they should of had instructions and stuff. Anyway, good luck with the sunshade.
