No, Oracle 651 is not recommended for long-term use on car exteriors. While it's a popular and affordable cast vinyl for craft projects and short-term indoor applications, it lacks the durability, flexibility, and adhesive properties required to withstand the harsh conditions a car faces. Using it on a vehicle will likely lead to premature failure, including fading, cracking, and adhesive residue that is difficult to remove.
The primary issue is that Oracle 651 is a calendered vinyl, meaning it's manufactured by being pressed through rollers. This process makes it less flexible and more prone to shrinking and cracking when exposed to constant UV rays, extreme temperature changes, and weather. Automotive wraps require a cast vinyl, which is manufactured differently, resulting in a more conformable, durable, and UV-stable material that can stretch over complex curves and last for years.
Furthermore, the adhesive on Oracle 651 is not designed for automotive paint. When removed after being exposed to the elements, it can leave behind a stubborn residue or even damage the clear coat, leading to costly repairs. For any exterior car decal or wrap project, you should exclusively use vinyl films rated for automotive use, such as Oracle 751 or products from brands like Avery Dennison and 3M.
