I dont know the make up of the flash copper....but, I do know you will be better off if you just sand blast, blow off your part and start your plating in the strike bath. Try to go into the bath with the power on and at the highest setting it will allow. Back off the amps after a min. of plating. Basically your trying to get the plating on as fast as possible so your base metal wont corrode. IE...Turn black!
I use a neutral nickel bath and have used copper cyanide in the past.
It seems any time you introduce fresh/raw potmetal to anything but air.... you run the risk of reactivating old corrosion deep inside the metal. I have had some parts blister after a month..(depresing!) But, that is the nature of potmetal/zinc alloys.
To me it seems that sandblasting with silica sand is the best way to remove chrome/old nickel/reactivate old nickel and corrosion in one step.
Good luck and keep at it! It takes time and patience...im still learing after 3 yrs!
Also...try and get some type of power supply that you can adjust. Its really the only way to go. Check here for some or E bay for bigger units.
