Vehicles can be driven away immediately after application. Exterior surfaces can be lettered in damp conditions or when rain threatens. Even on dry days, a wetting solution is often used on the surface to help in positioning before the graphic is burnished down for it's final placement. On the caution side, there are some limitations and special circumstances to watch for. Vinyl comes in different grades and need to match the intended use.
Promotional grade is for interior use only.
Intermediate grade is rated for 4 to 5 years outdoors and is the most common. High Performance grade is the most durable and expensive, rated for 7 to 10 years outdoor life. Vinyl has a physical cutting limit. At some point, the friction of the cutting blade overcomes the strength of the adhesive holding the sheet to it's backing and the whole job gets tangled up in the blade. Even if you get a successful cut, it may be impossible to weed.
