Radio reception question

Thanks Dart, you are the man I thought would know this.

That is a great idea with the aluminum paint and ground wire. I guess most of the aluminum-coated underside could then be painted over with body color.

Is the crux of the problem shielding the ignition components or something to do with radio wave propagation or both?

I will share this info with the guys in the Body section, if you haven't done so already.
