How often should Nickel Guard be re-applied?
It depends on use. If you are wearing the item regularly and in hot or moist conditions, re-application more frequently will be necessary. If you are unsure whether reapplication is needed, test the item with Nickel Alert! Nickel Alert was designed to test without destroying the barrier properties of Nickel Guard. Tips for maximum protection: – Apply three (3) thin layers of Nickel Guard to your item. Let each layer air dry a minimum of 15 minutes before next application. -Take care to coat the areas where metal makes contact with the skin.
