Apply to clean surface. It is necessary for surfaces to be free of all dirt, oil, Silicone, etc. as these can cause adhesives to fail as well as reduce the life of decals and striping.

Applications should be made when surface temperatures are above 50° F.  Applying to surfaces in direct sun and hot may be difficult. If possible, apply to surfaces that are in the shade.
Surfaces that have been painted need at least 72 hours for the paint to completely cure and “gas out” before applying vinyl decals or reflective striping.
Do not use liquids to apply any reflective decals or striping, as this will cause damage.
