Isopropyl Alcoho (Rubbing Alcohol/Roger)

[Roger Jolly]

Hi Joe,
               That's the stuff I use, never thought about there being 
different qualities. And yes I use it straight out of the bottle.  Just 
checked, it is Isopropyl. I agree there is more than enough water in there 
to do the job.  So take your flame suit off.  <G>

Regards Roger
