Clean surface you are applying the material to. You may use a commer-cially available cleaner designed for auto finishes. When it is time to spray the material peel backing from material exposing the adhesive. Spray material with a light amount of the soap and water mixture. Simply mist the material This will help the adhesive from not sticking right away till you get it in place.
Place the material on the vehicle. Align the material on the vehicle. Use the bottom edge to follow the crease in the rear door. Matching the side curve to one side of the door apply the vinyl across the door keeping it aligned with the crease in the door. Be careful not to stretch the vinyl. If the vinyl is too long it means it was stretched as it was being installed. Simply remove and reapply. If it was too short it can be gently stretched longer as you get to the end of the install.
After the face of the door is finished simply wrap the vinyl over the top and down the inside of the door.
Once the material is in place you can use you hands and rub the surface pushing the excess water out from underneath the material. Don’t rub as hard as to move the material. Use you hand as it would be a squeegee. You can use a squeegee but it may be awkward on the textured surface.
You can install the material if you use very light pressure when applying till you get it in the proper location. You can peel back the material and reposition it. Once in place you can apply full pressure to the material. For this products this technique may be the difficult approach.
After installation you would do best by leaving ample dry time before driving or washing the vehicle, if you installed the recommended wet method. This is a permanent adhesive on this product. Great care should be taken if it is needed to be removed later.
