Nickel SmartNickel Guard® Single Pack - Protective coating for metal objects

It smells like strong nail polish, but it goes on just as easy, and dries clear in minutes. I cleaned the green and black off of all the pain- inducing earrings I bothered to keep with jewelry alcohol (90% alcohol, I highly recommend for use on your phones and jewelry during these pandemic times.) Then I painted the Nickel Guard on. Since then, my ears have been able to heal and I experience no irritation. Being similar to nail polish, I expect the product to rub off on the backs and on my skin, so I plan to repaint in a few months. For the size of the bottle, you can do a whole jewelry shop worth of earrings, so be generous and get the backs and reapply so you don't have to suffer anymore.

I spent a lot of money on an anniversary ring for my wife, only to see the ring laying on the counter in the kitchen...she explained that she was having break outs on the finger she wore it on. I bought this product and applied about 3 applications to the ring...she has not taken the ring off in about a month now. It works!

Bought this...applied to studs of earrings and let dry overnight. Made my ears but immediately when I put them in the next morning. I took them out and burning stopped. Tried to return and discovered they will not take back if used. Buyer beware.

used on ear rings

We got this to coat the inside of a ring that was causing some allergic reaction after being worn for many years. To be honest we don't know if it worked or not, it went on and after that it was imperceptible. The rash did go away but that may well have been from a different kind of washing, or cleaning the ring. Nothing against this produce, just not 100% it was what we actually needed.

I Purchased This for My Rings. I Was Skeptical b/c I Had Tried Other Ways to Cover the Inside of the Ring, but Nothing Worked. This WORKED! I'm Impressed with Your Product. Now I Can Wear My Favorite Rings Again. Thank You, What a God-Send.

I suddenly developed a reaction to my Apple Watch. Found this product and it’s working for me. So glad because I truly love my watch.

Expensive for a small bottle. Easy to use
