Another recent question got me thinking about this. Will a ground to the frame work properly if the bolt is powder-coated?
Since I don't have any skill, tools, or ability to powder coat, whats the best way to make a ground connection to the frame or block in a way that will prevent rust or corrosion from forming? Maybe a different way to ask is this:
Is there a chemical coating or treatment that can be applied to a clean, metal to metal, soldered and crimped ring lug ground connection that will prevent rust or corrosion from breaking the connection? I'm thinking of the screw holding the ring lug and the bare metal beneath it rusting and how to prevent that.
I'm asking in general, but the application would be for a 2000 Toyota Camry with 142k miles on it.
