Thankx for the above comments. According to my local paint stores that I talked to, the denatured alcohol just doesn't seem to be available any more and the next closest is methyl hydrate. Its listed as 99.9% pure alcohol. It also says you can use it for camp stove fuel and is readily available. I picked up a 1 liter bottle an tried it. It works great for thinning epoxy and also cleaned up some spilled Ca that I had spilled on the counter top.
