After you have applied two coats of the Copper paint (or Light Copper) leave two dry..
Wait 2-3 hours between coats.
Apply the Activator (Reagent) in a random way - sponge. spray or drip for an authentic look.

OPTIONAL:
Insulate the base with the appropriate Primer.
Once the desired result is obtained, when everything is dry, apply 2 coats of Anti-Oxidant Varnish to block the activation/oxidation process, waiting 2-4 hours between one coat and another.
