There is some good and simple instructions here:

Surface temperatures should be between 50 and 90 degrees Fahrenheit before attempting the installation. As a general rule, if the surface is hot to the touch it's over 90 degrees Fahrenheit. Adhesive becomes brittle when it gets too cold and gummy when it gets too hot. Applications outside the recommended range of 50 to 90 degrees Fahrenheit reduce the adhesives' ability to perform.

Application Procedures: You can choose to apply vinyl in one of two ways; dry or wet. Applying vinyl graphics dry does not allow for any mistakes. Once the vinyl touches the surface, there is no removal without damage.

However, applying vinyl graphics with application spray (soapy water) allows you the opportunity to remove and reposition vinyl as needed for up to several minutes. For obvious reasons, this method is recommended for both beginners and experts. To apply using the application spray, spray the surface thoroughly. Then lay the vinyl on a flat surface and spray the adhesive side as you remove the backing. An extra set of hands is a good idea. Then simply apply the vinyl to the surface.

Do not excessively stretch vinyl during the application. Because vinyl is a pressure-sensitive product, a squeegee should be used for all installations. The purpose of using a squeegee is to remove the excess fluid and or air from behind the vinyl. You should always start the squeegee from the middle and either use a straight up or down motion. Allow the vinyl to set for 5 to 15 minutes.

When removing the application tape, always pull it slowly, back onto itself, at a 180-degree angle. Bubbles should be punctured using a pin. Do not slit the vinyl to release the air. If the vinyl is slit it will spread or gap. The cutting or trimming of any stripe or graphic should be done using a very sharp knife and very little pressure.
