Silicon on ground?

[digitalrainman 10+ year member]

I plan on changing over my ground tonight to a bigger bolt and sanding down the paint on the floorboard of my truck. I plan to spraypaint over the bolt and ground connection onces its in after sanding in order to prevent rusting. Would it also be fine to use silicon caulk for any extra prevention of water getting under the washer and rusting? Are there any problems with using silicon caulk on electrical wiring? Where i would be putting it is just around the washer edge so water doesnt get up under it.

Dont ground to the body. It would be better to run a ground directly to the frame.

+1. Your truck has a frame, which has a lot less resistance than sheet metal. Be sure to add a ground wire from the frame to your battery too.
