Thick copper plating to fill pits and stretch marks in steel

I have started a mobile plating service in this area and have done quite a few gold jobs but I have been questioned about chrome so I bought a starter chrome brush plating kit. I understand that it is a three step process but I have also been reading about copper plating here on this site the copper plating I received in my kit is a cyanide base. I understand this is best for adhesion but what other copper solution should I use to fill in stretch marks in steel such as old valve covers. I know I could spend hours polishing them out but would rather fill them.

Any help would be greatly appreciated thank you very much,

You can try to fill pits with zinc dust [on eBay or Amazon] / 'water glass' [on eBay or Amazon] mixture; when dry, sand it and (up to 48 hours -- it depends on thickness) plate copper!

Good luck!
