Yes, you can wash your car after you wrap it. Although, wait at least 3 days before you do so. DO NOT take your car through a drive through car wash. ONLY WASH YOUR CAR WITH A TOUCHLESS WASH. If you take it through a touch car wash like a gas station, the brushes will scratch or potentially peel your wrap. Only hand wash your vehicle or have a detailer do it that is experienced with vinyl wraps.
