If you want to apply car decal to a particular area, they must first clean the area where the decal has to be applied. If you apply the sticker on the dirty surface, it will pick up the dirt and may lose the stickiness. So it is better to make sure that the area is clean where you want to put the sticker or the car decal. To clean the surface, you may use soap or rub the area with alcohol or clean the area with water.
Even before you put the vinyl car decal just be sure of the location where you want to put it. Some locations where most of the decals are installed are bumper, windows, and the interior and the exterior surface to give a stunning look. Some enthusiasts put the decal on the tires as well to make the car look more appealing. Once you have identified the area just care to stick the vinyl car decals in that area. Step back a bit and see how it looks like. Once you find the most suitable location just apply the decal permanently.
Peel the paper backing off the sticker and make sure that you are not touching the decal. Finally place the decal precisely and smooth it out until it is placed properly. Just trim it and remove all the bubbles away from the vinyl car decals you have decided on. You may use a pin for the purpose as well.
