hey guys,
as to the nitro, it like all solvents needs to be used with caution, ventilation, skin cover, and a respirator. it is a VERY good solvent for many things, CA among then. industry use of it in many hard to dissolve lacquer and epoxy components. a small % makes a very large difference. we have used it in the blending of fuel for many years, with a LARGE dolop of caution. i have not purchased any since they made N H R A go to the 90/10 mix, i would assune that it still contains the peroxide indicator, which turns blue when in the presence of. if that happens, you need to get rid of it SOON. it will become very unstable== poof== not good . i've seen only time when it happened, SURE GOT MY ATTENTION> be safe, live longer, enjoy the hobby.. echo on all the advice on above entries. just need to fuelpruff any wood on the front end of a fuel burning plane, with oil in the mix. thanks frank

see ya
