Random paint flaking/chipping on undercarriage

[Krypt]

Seeing if anyone else has noticed any random paint flaking or chipping from their undercarriage on the cab/bed main floor boards. Some might see this as a minuscule issue but I want to address the little issue ahead of time before it could potentially become something much worse later on. I crawled under the truck last night because I was bored and had some extra time. Everything looked fine when I saw on the cab floor board/cross member 2 little areas where it looks as if the paint/primer has chipped or flaked off. There doesn’t seem to be any signs of impact from something that could have flung up there and did this damage. Just seeing if anyone has noticed this on their truck and what did they do to fix it? It appears to be bare metal and I don’t want any surface rust presenting itself. I would also like to match the primer or paint or whatever was used so it looks all original. Thanks.

If it is hidden from sight, I would just mask off a square around it and paint it with black tremclad or equivalent. Not a big deal to paint those area's black, but you can buy the touch up paint from the dealer or order it online most likely. Most important thing is to protect it.

It's aluminum isn't it?

The tires on these cars pick up and throw a ton of rocks, you may be fighting an un-winnable war.

While aluminum doesn't rust per say, I have seen a lot of aluminum components rot away or corrode from the elements. Maybe Ford is using a better grade too though, IDK.

Military grade. lol. Sure any metal can corrode I guess. I just wouldn't be worried about rust. Most aluminum corrosion I have seen was from touching a dissimilar metal, not from general exposure. But who knows.

You're correct, dissimilar metals are the worse, on connectors in Substations the aluminum hS to be on top and the copper on the bottom with proper inhibitor used which we call mother-in-law?

Don't ask me why the mother-in-law name because I don't have a clue.

One guy stated the older black inhibitor was actually called mother-in-law but the new improved inhibitor is white.

Please don't flame me for this statement above as there's no racial intent.

Sorry that is racist, it should be father in law or "any" in law, lol

Sorry I couldn't help it, but reading that made me laugh.

Same as anti-oxidant used on aluminum conductors at panel lugs?
