Painting the bare metal underneath Hinges?

[JTGuy]

I just don't let mine get wet. It was designed and built in dry buildings so why would I think it would like being wet. LOL. Mine I garaged and we get just a few days if rain here. I just keep it waxed so seldom hosed down. If I start to see the paint failing it will be gone.

Lol... damn it knew I was doing something wrong

What if you sprayed the hinge area with a WD40 type oil and wiped offf the excess.
Or Just wrap it with a nice color and call it a day.

Better off using something like Ballistol but I doubt it would do much good either.

That may be - but true galvanic processes rely on water (and salts of any sort make it a lot worse)

But then - I'll pit my meticulous care against many out there. There's a reason I have a nearly perfect 196 out of 200 point 42 year old car with 3 gold wins.

If it's a true factory problem, it won't matter how things are taken care of.
If it's galvanic reactions, it will matter.
The problem is, we don't know the exact metals involved - we don't know the exact aluminum skin alloy or even the composition of the hinge.
On the other hand - forum members have shown bubbles on the tail gate - not at the edge and not where any other part bolts to it.
That makes me scratch my head (and risk what hair is left) and wonder- WTH is going on there??

What if you grounded every body panel to the frame? Would that slow the corrosion process?

It would have to be done in such a way that there was no variation in the resistance of the leads to the frame. Any variation in the resistance will cause a voltage drop of differing amounts between panels.

I recall a stereo guy warning me about too many grounds resulting in ground loops because they might have different potentials, leading to a voltage difference between grounds.
