Denaturants are specified based on the work being done. Our anhydrous 
alcohol that we sell for shellac is denatured with 10% isopropanol and 
5% methanol. JFYI.

> Given yet more bad news on benzene (often the denaturant) you might want 
> to go with the expen$ive Everclear solution, or the cheap 99% isopropyl 
> (propanaol) solution, rather than continue playing with denatured 
> ethanol if benzene is the denaturant used.
