i’ve used brk fluid long after breaking the seal; i figure it’s no more hygroscopic in bottle than in car, unless bottle is big/nearly empty and able to hold a lot of moist air. anyway i didn’t notice any issues in my cars.
you can mix certain dot rating/types like Glycol-based (DOT 3, 4, 5.1); they do not mix w/ silicone dot 5
