Using these pinstripes is easy. First, make sure to clean the grille surface thoroughly. You have two installation methods: wet or dry. For the wet method, wet the back of the vinyl with a bit of soapy water. This gives you more time to adjust the position but you'll need to wait for it to dry completely. For the dry method, start near the emblem and slowly work towards the corner. Do the same on the other side. If you stretch the material, use a credit card to tuck in the end. Remember, the lower S208 pinstripe isn't included in this set. When it comes to maintenance, the material is durable, but avoid using abrasive cleaners. Just a gentle wipe with a soft cloth will keep it looking good for years.
