This patina was made specifically for use on copper. It will not work on brass or bronze.
This is a cold patina. Please allow an
hour or more for the patina to work on the surface of the metal in order to
achieve the best results. The metal must be very clean and should be
buffed or polished prior to application. Be sure to remove all of the
polishing compound - rubbing alcohol works best to remove the final buffing
compound residue.
Application of Rainbow
Patina:
Apply the patina to the surface of the metal; let it sit for about an
hour, then rinse with water. If the patina has not reacted enough, reapply and
repeat the process. When finished, allow to dry and spray on a
lacquer.
Here is the formula:
One gallon distilled water
½ ounce muriatic
acid
½ ounce sodium thiosulfate
