Finishing Instructions:
The topcoat lacquer is designed to protect the metalized surface and to change the metallic appearance into any color metallic effect desired. The proper toner is added in correct concentration to yield a brass, gold, copper, bronze, or other metallic finish.
The metalized piece still should not be handled with bare hands until it has been protected with a topcoat.
The color topcoat is sprayed over the dry piece being careful on the first pass not to flood the object with a very wet coat. A very wet coat will yield runs. It is important to put a mist spray on first and then on the second pass a slightly wetter coat. This yields a more uniform color.
This topcoat will set-to-touch quickly and the work can now be handled.
Antiquing or further decorating can now be done fallowed by a final clear topcoat layer if desired.
A suitable air or force dry is recommended prior to packaging or final assembly.
