I haven't gotten my feet wet with diesel yet; although my buddy has a 2.5cc PAW diesel that he ran for me once. The smell reminds me of hanging around the big airports. A very pungent smell, no doubt.

UPS charges 25$ hazmat, plus ~$10 normal shipping rate for a 4-gallon case (1 or 4 gallons doesnt matter), which is why glow fuel is so expensive up here (roughly $32-$39 a gallon). Thats why I make my own. Torco sells nitro for about $56 a gallon with free shipping which is a steal, IMO. I have already made probably 6 gallons of fuel using 1/2 gallon of nitro.
