After you wash your camper, it is OK to water float the decal on the side of your camper. After you squiggy out the water from the decal, it will be fine. The water floating process is only to aid in the correct placement of the decal so that you do not stick it on crooked. It buys time for amatures like us. I have floated new decals on a 2008 Scamp
16 SD deluxe and squiggied them out and they looked great and have remained on the camper for the past 3 years. That is also how the local sign shop does all of their vehicle signage and windows
for store fronts. If you stick them dry, they are stuck where they stick, right or wrong!
