The side stripes are easy to install yourself. I used 2 drops of dish washing soap to one average size squirt bottle. I sprayed the body, then applyed the stipes, while using a body puttly type squeegie to work out the solution, working from the center to the outside. As to the roof, that too may be same proceedure, but I ruined the hood vinyl, as it tapers from out to in as the hood slops from windshield to grill. I had to buy another and have that one done by an expert. They used a heat gun to stretch it and prevent the wringles as it tapered down.
They can be applied dry, but you better be a pro to do that!
