It is really nice - if you defraud the tax-man by drinking that alcohol,
you dead :)

I usually buy it from Farnell, in 1-litre can and in aerosol form, made
by Electrolube. Here is the data sheet
http://www.farnell.com/datasheets/316731.pdf
It claims 99.7% purity, 0.15% max water content (I suspect that the can
quickly exceeds that content once opened...)
