Grounding the battery., What's the proper way? Options

[Bob L.]

I have just finished moving the battery to the front trunk. so far I have the ground cable bolted through a pre drilled hole in the front trunk. I scraped away some paint/coating to get to bare metal, for a good ground. So far it all seems to work fine. I just don't feel like I should leave it like that.

Is there a proper way to prepare the sheet metal/bolt/wire to prevent corrosion from the current or moisture?

OR... should I just coat it over with a protectant spray now that it is done?

Thanks,
Bob.

If you are overly anal and $ is not a problem, then there is a copper brush on coating that actually plates a bare metal surface.

Then when I attach a ground stud to bare metal, I use one of those "star" lock washers to get a good bite.
Finally home depot sells a CRC lube that is supposed to drive water out of, lubricate & protect electrical connections.

For low current connections I do as they say above, but I would treat the battery differently since that connection will see greater than 100 Amps when cranking the starter.

... wanna reinvent the wheel?

The stock ground lug is brazed in place BTW. Doing it as good as stock is not "re-inventing the wheel" IMO.
