Thanks dubsport. A few high spec mk2's are popping up but you know where you saw it first.

Sean it was a home made kit but needs to be under strict control (safety and mixture) or it wont plate. Id just hand them to a plater next time. Save the headache

If you do want to diy you need a voltage regulator, zinc chloride and ammonia chloride but the mixture has to be perfect. Ball ache
