The best way to avoid bubbles is to take your time and make sure you have a clean surface. Squeegee the kit SLOWLY, press FIRMLY, from front to back, working from the center to the outside, doing small sections of the kit at a time. Even then, you can get some small bubbles that can be removed later by using a pin or sharp blade to cut the edge of the bubble and work the air or water out through the opening. Decals can be installed wet or dry, but it is safer to install a kit wet. It can be pulled away from the vehicle during installation in case you get a fold or large bubble. A day or two in the sun and they should come out on their own. You may need to help push them out with your fingertip. You can also use a pin to make a small hole and let the air escape. A dry installation may have fewer bubbles at first, but its a one-way street, and there’s no turning back. Once it’s on, IT’S ON!
