Clean car well to ensure good adhesion of the decal. Fill a spray bottle with a mixture of water and soap (we use baby shampoo), about 4 large drops per 32 oz. spray bottle of water. Be sure to install decal out of direct sunlight. Also having someone to assist you if you can is very help-ful. It may be necessary to separate multiple decals on one sheet by cutting with scissors. 

Step 1:  

Spray car with a generous amount of the soap and water mixture. 

Step 2:  

Peel backing from insert exposing the adhe-sive. Also spray back of decal as your peeling the backing paper off. 

Step 3:  

Place decal on the car. You will be able to ma-neuver the insert into position because of the soap and water solution you sprayed on earlier. 

Step 4:  

Squeegee out the water from underneath the decal with a squeegee (covered in a cloth that will not scratch the vinyl and keep the vinyl wet). 

Step 5:  

Use a hair dryer when needed to help the vinyl conform to the surface and help dry the under-neath so the vinyl can stay in position. Once the vinyl has conformed to the shape of the car let it cool, holding it for a moment. 

Leave several hours, depending on climate, of dry time before cleaning car. Use a quick detailer in a spray bottle for the initial clean-ing then hand wash car waiting at least several days for the first time after drying. Do not power wash vinyl or wax vinyl.
