DeNatured Alcohol is ethanol with 'denaturants' added, so it becomes undrinkable.
If they sold pure ethanol, then drunks everywhere would not buy any branded alcohol, and the government would not be collecting their liquor taxes, which of course is intolerable.
I believe in Australia and New Zealand they call DNA, methalyated spirits. Methanol if injested can make you blind. Its showing up in hundreds of hand sanitizer products these days, and is toxic. Not sure methanol is the denaturant added to methalyated spoirits, or just one of many.
Not sure all what type of denaturants they add to make it undrinkable. It likely varies among brands and countries.
I've never tried spraying it on a hotcoat. the ethanol might evaporate and be inconsequential to the cure, but those denaturants? I know not.
I thought white gas/ camp fuel, is pure Naptha.
I recently tried to use DNA as a fuel in my multifuel camp stove, which I always desired to use 'white gas, or coleman fuel' and it did not work properly. I think I would have to change the jets.
I have used kerosene and both leaded and unleaded gasoline in this stove before, but coleman fuel/white gas was the cleanest and most desirable fuel to use.
Yes I have just noticed in the last year or two here in the U S they are labeling DNA as camp stove fuel. Here in the Northwest a lot of boats have Alcohol stores in the galley. Also most of those little back pack stoves(at least the more expensive ones) are Alcohol stoves. The old Colemans were white gas. Newer ones are Propane. I think white gas has been more or less phased out due to it's stinky smell and the fact that it is pretty pollutant. Alcohol burns pretty clean. You are correct in your definition and yes you would have to change the jets for Alcohol to burn properly in a stove that normally would use white gas or Coleman fuel.
