Copper plating steel or aluminum motorcycle gas tank and frame?
Q. I've searched on the matter but have not found anything for my situation.
I'm thinking of a paint scheme for my bike and would like to know if it would be feasible to copper plate a steel motorcycle frame and (maybe aluminum) gas tank. I would then paint over some of it (stripes, etc). I'm wondering how hard the copper would be, how resistant to scratching or if I can do something to finish (i.e., clear coat?) it properly. I would also like to venture into copper plating the aluminum motor (1970s motorcycle). I understand that these parts need to be properly polished BEFORE plating? Is this all pie in the sky? Any advice / criticism is much appreciated. Would someone take a wild guess as to cost? (i.e., over 500$ over 1000$)
Being a hobbyist, I would try to do much of the prep polishing.

A. Orange County Choppers has done a completely copper plated chopper, so, yes, it can be done. >$1000, maybe >>$1000. Amateur polishing will probably not work very well. Take it apart and send it to a custom plating shop

Q. Can you mask an area of the tank and chrome the rest of it? ie. I want a copper stripe running across the tank. I assume I have to completely copper plate it, then mask the stripe, then continue onto the chroming process.
Also, can I clear coat over all of this to avoid the copper from oxidizing? Would normal clear coat work?

A. Virtually any combination of plating and paint you can dream up is possible... however you will have to find a plating shop which is both equipped and willing to do the work. Talk to them about what they can and will do.
This is not a home project.

A. This sounds great. Keep in mind, that all copper plating is subject to oxidation immediately indoors. I have been in the Navy and seen what copper looks like exposed to the elements. Cover your copper with a clear coat or an epoxy at the bare minimum, and expect a great deal of attention to be paid over time to ensure you have a shiny work of art. I want to do copper plating on a few things using a brush-on technique of copper sulphate. I hope that it stands up to the open-air application I have in store for it on my Suzuki Boulevard!

Q. Hi
I'm customising an old BMW motorcycle and would like to copper plate the rocker box covers.
They're a non-steel casting, I presume an alloy of aluminium or zinc.
Its an old bike, and I'm keen for the copper to age and patina, so a bright finish is not required, but I'd like to to be reasonably durable and abrasion resistant, so I expect to need a reasonably thick coating.
Can you recommend a good process to use, which will help me locate a suitable electroplater (ie once I know what I'm looking for)?

A. Copper is not very durable nor abrasion resistant. You can let the copper age an patina or force patina using a patina solution, then just clear coat it using a coating designed for it. A clear coat that is not glossy at all that will kill the natural patina effect, the clear coating using 2k or catalyzer will give you a durable surface.
