All of our vinyl decals are custom made for you, but we always recommend measuring your truck door or the area where you will be placing them for optimal aesthetics. We have a team dedicated graphic designers that will be happy to help you if you need it. When viewing a product, you can Request a Proof, and one of our graphic designers will send you an image before production. When you receive your decals, make sure the area where you will be placing them is clean and dry. All you have to do is remove the white backing from the 3 layers, and press the transfer paper with the vinyl on the surface. Once it's on the vehicle, make sure to press hard for a few seconds with the included squeegee then remove the clear transfer paper, be sure to take your time so you can do it without mistakes.
