Brake fluid would etch the glass of the lenses. Cleaning the surface wouldn't return the camera to service. Better than paint would be any other substance to thin out the brake fluid for application, particularly if it were less noticeable than paint. That would cause the repair order to come in from lost data collection rather than a report of vandalism, denying them creeping time and that sweet, sweet data. Definitely don't do that.

I didn't know that, and I have used liters of the stuff. Learn something every day.

Is it just Dot3? Dot4 is more common these days.

BTW, kids, we are talking about brake fluid, so don't go spraying it on your camera lenses!
