Hiding metal surface defects

Hi!

After polishing and final diamond lapping surfaces of ferrous metals (medium and high carbon steels) ,gloss is achieved BUT due to forging defects etc, I face problems such as surface "pitting" and at sometimes "grainy" appearance. I would like to know whether there is an economical "HARD-CHROME PLATEABLE" metal filler which can be employed to solve the problem .

Yes, fill those imperfections with a nice Watts nickel or sulfamate nickel electroplate.

Many thanks Mr. Pullizzi!

Just one more question to that..will Nickel electroplates prior to hard chrome deposition withstand pressures, temperatures, conditions for injection moulding up to machines having 1200 clamping pressures and about 500 °C molten plastic flow? As we are working upon injection moulds, hand moulds, blow moulds, compression mouls, etc..
