Another thing you should never ever do: mix paint and dot3 in a handheld pressurized garden poison sprayer.
Be aware brake fluid is like antifreeze, it tastes good to animals if they don't put bad taste in it, and kills them.
They're dying for an honorable cause. /s
Why shouldn't dot3 mixed with paint? Just so I know why to avoid it.
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!
guessing because it goes through the sprayer
Thins the paint's viscosity down maybe?
What would brake fluid do?
Why not?
Because that would be illegal, and advice in easy-to-acess ways to sabotage fascism should not be shared anywhere.
