Nitro-methane is almost impossible to buy around here except in large quantities...Years ago some of the fuel guys used nitro-benzine in place of the nitro...made your fuel smell like shoe polish, but don't think I saw any damaging results..anyone know of a way to get past the nitro supply problem...one supplier said he couldn't sell it staright anymore since 911...it has to be 50-50 nitro and alcohol....any replies on this ...curious..
