When I watched the video it looked like the smoke had a blue tinge (wtf, where did that word come from?) to it, like oil smoke. However, it didn't seem to hang in the air the same and not as thick as I'd expect.

...just thought I'd comment, wish I could actually give advice or help or some such thing.

edit: I apologize in advance 'cause this is completely off topic but one of the related clips I decided to check out was a 2dr. version of my car being smashed by an SUV. WOW, I knew my car wasn't safe but actually seeing what would happen... the unadulterated horror of it... what's worse is in my area there are LOTS of less than stellar drivers behind the wheels of truly massive pickups and SUVs. :feelslikeapieceofchinainfrontofabull:
