It's not really a good idea. Denatured alcohol is ethyl alcohol, the kind you drink, with something, usually methyl alcohol added to it so you can't drink it. Methyl is absorbed through the skin and turns to nasty stuff in your bloodstream. Just as a sidebar, this is one of the best examples of regulation gone bad. We've taken one of the few non toxic solvent/fuels available and turned it into poison so the feds could collect the liquor tax.
