I have the same MFH-kit in my to-do pile and am looking with great interest. I also thought about the chrome parts. Since Alclad chrome is not the ideal solution to replicate chrome because of the fragile pant effect, I was thinking about other ways to do these parts. Plating seems to be a logical step, but the kits I have seen so far all used thick primer which needed to be brushed on. This primer was metal loaded to conduct the power. The wanted effect was then created by choosing different agents.
Works OK, except for the fact that this "primer" is thick, must be brushed, cannot be polished and thus gives a poor final effect. Plus the nickel turns black after a while, like silver. So it needs to be re-polished with silver-polish. So that was a no-go.
Aren't you afraid of having the problem your nickel will turn black in time?
I was considering preparing the parts, and then send them to a professional chroming company.
By the way, very nice work so far! Thanks for sharing your experiences.
