Do not do it with the stuff still in the car. I feel so light-headed...:cool Seriously, I feel like crap. About half-way through I got a giant whiff of the propellant for this stuff right in my mouth. Oh my god it was gross as hell, I tried to throw it up, but that didn't make a difference. The taste was still in my mouth, ugh... I bust people for huffing paint, and I believe I just did it... Shoulda worn a respirator.
