What vehicle's fluid can eat through clear coat?
My car was on an auto transport but it was underneath a car. My car had fluid on the hood that leaked from the car above. I thought i could wash it off but it etched into the clearcoat. And the car was only on the transport for a week! What could this fluid be? Brake fluid? Trans fluid? What could be so acidic? Not oil.

Dot 3 (I think) brake fluid will do it.

Probably brake fluid, that is pretty corrosive to paint. Coolant can be also, but usually only when it's hot. How big/bad is the spot?

I wet sanded it out pretty good, but I can still see it at the right angle. I'm borrowing a paint thickness meter and see if I can go down anymore. Thanks all! |

Brake fluid is by far the most corrosive but it would have completely ate through the clear coat if it was on that long. Any fluid can, especially used fluids that have contaminants, could cause some etching if it's allowed to sit on the surface and dry for an extended period. |

Yeah, I doubt it was brake fluid. Anything more than a few minutes and the paint is gone with that stuff.

Agree with everybody above ..... brake fluid is very aggressive and will eat paint.

Re: What vehicle's fluid can eat through clear coat?
ethylene glycol coolants can mess up the paint a little bit. Yes brake fluid or clutch fluid as already mentioned can really do a number.

Brake fluid and coolant are two corrosive fluids that I know of.

Hyrdraulic oil from the cylinders that raise/lower the car ramps on those rolling parking lots?
