This problem isn't restricted to aluminum chassis. ANY riveted ground

I used to use copper pop rivets with steel chassis. After the items
were riveted, I used a 80 watt soldering iron to solder the inside end
of the rivet to the metal socket or terminal strip, and the chassis. I
NEVER had a grounding problem when i used this method.
