huh, they say graphite in pencils are poisenes and cause cancer. nearly everything "causes cancer", by the way they are talking about pure nitro methane we are talking about 20%-30%. not 100% if it causes cancer than uh ohh because im around protrolium distillates, grease,cuso4 (batt acid), lead, copper, graphite, silicone. all day every day.
the fumes are the most dangerous of all, at first i was around my nitro evader (still am) the bunt fumes gave me a head ache dry nose and more, but now im immune to its abilitys to irritate!!
no gas is going to make me uncomfortable!
