GP Allyseal Zincate is a non-cyanide zincate designed specifically to improve adhesion and allow the plating of various metals onto aluminium and some aluminium alloys.
 
The zincate applies a dense surface layer onto the aluminium in an electroless plating process that involves either a single, quick dip or a double dip process.
 
Once finished, you can use nickel, replica chrome or zinc to electroplate on top of the zincated aluminium.
