How do you coat tarnished nickel?
Nickel that has been in contact with oxygen for a long time will form oxides. You can remove these oxides with our Nickel-Strike and at the same time build up a sustainable nickel layer. Then you can apply the desired coating.
Pre-treatment with Nickel-Strike is not necessary if the nickel layer was applied immediately before the subsequent coating. A new nickel layer should be coated within an hour, as the oxide layer builds up slowly.
