I had an Aprillia RS125 frame chromed for a customer some years ago, and wheels anodised for quite a few moto-x bikes
Thinking alone the lines of C90/Maxi/Bantam & maybe when I'm alot older ............ ...some esoteric but notable classic..
To do galv you need the metal to be perfect. If it's old, the process will dissolve your frame. I think a cub frame is too thin to take galv at the back
