Today's Aerosol's are crap

I think the EPA clowns cracked down on the chemicals previously used as propellants. Now whatever we are stuck with leaks out, like the tiny molecules of helium leaking right through the material of balloons.
Now I buy WD40 in the metal one gallon can and pour it into a reusable spray bottle, so it no longer relies on aerosol.
I gave up on Mopar Performance engine paints. They were crap years ago.
