Brake line corrosion prevention

[auto-x fil]

I found some heavy, sticky, almost waxy grease-type coating smeared all over the brake lines on a used car I purchased. It appeared to have done a wonderful job of preventing rust of those lines. I haven’t been able to find this product via google.

Has anyone seen such a thing?

Thanks!

Maybe it’s fluid film. I do the bottom of my truck with it every year

This is much thicker and greasier than fluid film or other corrosion-prevention coatings that I’ve been. It must have been applied with a gloved hand. It’s almost like a wax, as it’s firmer than even a very high-viscosity grease. It’s not rubbery at all, it looks to be quite old and is still soft and smear-able.

Think peanut butter, in terms of consistence. But more waxy and less drippy… maybe room-temp cream cheese.

I bought a foxbody that had something like that on the inside of the panels. Kind of a gross yellow/brown waxy substance.
There was a zeibart sticker on the window so I assume they were the ones that applied the rust proofing.
There was no rust where the rust proofing landed but the rear of the car was eaten away completely.

Sounds like cosmoline

There was a thing called DynaCoat, IIRC, at least Dyna-some-damned-thing, that was applied with a spray gun. They would guarantee a used car. There was a penetrant/converter first step, that if you put that on a rusty car, the rust would stop, like magic. It sat for a couple days, then you sprayed on the thick waxy stuff over it. And it would kind of shell over after a while, but the inside never got really hard. You could press your finger and make a dent, even a decade later. I never tried to actually smear it.

Woolwax?
