That mech has come up sensational Nino that Plating kit has paid of from that mech alone.
The plating kit and process is involved, but well worth it "if" you want to put the time and effort into it. Results vary with experience, but factors such as temperature, metal type (and thickness) and preparation determine the outcome.
This game was chosen to experiment the process as it had corroded parts that I could not possibly source New or NOS. The plating process (learning curve included), has taken over 50 hours. That has to be factored into the total restoration time which is already well over 100 hours. As a hobbyist that enjoys doing this kind of work, it all just "fun". But if you were charging an hourly rate, you would go broke very quickly.
I agree, Daniel - The kit paid for itself just because it added another "string to my bow", and the satisfaction it gave to me after I had the process nutted down.
I would consider offering it as a service to fellow hobbyists, as I would not expect this kit would be justified to do one or two games.
