One of the most important steps to follow before installing your new deal is to make sure the area you are applying it to is clean. Any residue from car wash soap, wax, oil, gas, etc, will prevent your decal from sticking. We recommend cleaning the area you will be applying your decal to with rubbing alcohol or clean soapy water. Make sure if using soapy water the area is rinsed well. Then use a clean lint-free cloth to dry the area.
