Jarvis is my Co-Pilot Decal! Our decals are cut using a sign grade vinyl that is durable and designed to withstand the elements. The decals will hold up well in an automatic car wash. If you use the pressure spay car wash do not apply a lot of pressure directly on the decal. The decals will not adhere to a surface that has been waxed but can accept wax after application. The decals can also accept a clear coat if needed.
