Allow the vehicle sufficient time to acclimate to this temperature if it has been in either a hot or cold environment. • Surfaces must be clean and dry to make a proper repair. • Do not allow the resin to come into contact with the car's painted finish, wiper blades, or plastic trim as this may cause damage. Not all damages can be repaired to restore full optical clarity. IMPORTANT!
