I was getting loads of voids and inconsistencies with the lead, so I've had to consider other options. I was thinking of making either a conductive filler or paint to allow me to fill it in and still plate, but that's not looking so positive.
I have done some research and now there are paint processes that are just like chrome. I got a quote and it looks like plan b or c (whatever it is now) is going into full effect. Primer,loads of filler and even more elbow grease then off for the specialist coating.
