In the early days advertising on vehicles was limited to a small amount of numbers and letters laboriously painted by hand on each vehicle. The practice was not very popular and was expensive, not to mention the damage done to the resale value of the vehicle Today's technology has made the practice much easier and more attractive. Surveys indicated that vehicle advertising is as effective as billboards, the perennial leader in outdoor advertising.
Thanks to modern technology "wrap advertising" is the marketing practice of completely or partially covering (wrapping) a vehicle in an advertisement thus turning it into a mobile billboard. This can be achieved by simply painting the vehicle surface, but it is becoming more common today to use large vinyl sheets as decals. These can be removed with relative ease, making it much less expensive to change from one advertisement to another or to change vehicles. Vehicles with large, flat surfaces, such as buses and light-rail carriages, are fairly easy to work with, though smaller cars with curved surfaces can also be wrapped in this manner.
Recent advancements in vinyl development have led to new types of vinyls specifically for doing wraps, such as vinyls that feature air channels to prevent bubbles, and microscopic glass beads that prevent the adhesive from taking hold until squeegeed down. This feature allows the material to be lifted and reapplied as needed during the wrapping process, without compromising the longevity of the wrap.
Decals can be made to cover side and rear windows on a vehicle, though for obvious safety reasons, the front windows used by the driver are not covered. The decals on side windows are typically perforated so that it is still possible for passengers to look outside. A wrap must often be divided into a number of smaller pieces to appropriately cover any movable panels on the vehicle, such as the fuel tank cover, trunk openings, and other doors. Wrapping is also sometimes used instead of paint as a less-permanent way of applying its operatorís standard advertising than paint.
The wrapping material is made of a high-quality vinyl adhesive product designed to be used on painted vehicles specifically for wrapping purposes.
