The final stage to the process is to stop the chemical reaction with this anti-oxidant, this will stop the verdigris from developing any further and seal in your finish.
Making the magic happen:
1: Apply Rust or Verdigris primer (only required on metal surfaces)
2: Apply the product Rust or Copper randomly (combine as many colours as you want-all 4 look amazing!) and apply two coats. Leave to dry 2-3 hours between each coat.
3 : Apply the Reagent unevenly.
4: Apply Anti-Oxidant to stop the process and seal in the finish.
