I see, so any frame to body contact would not be good.
How about the other things like mirrors, badges, or anything else non aluminum? Same thing I suspect. I wonder how cars like our MGA with its doors, bonnet and boot being aluminum and the rest steel?
So how does the 3 wheeler deal with the dashboard? Is it aluminum? But they sell as an option engine turned dash panels that are stainless steel. Does stainless steel react to aluminum the same way?
