Denatured is okay for airline and pond use. Denaturing is just so humans cannot drink it. It makes then sick. I'm not sure where to buy 90%-99% isopropyl in bulk. It should be available in 5 gal containers, but I don't know what specific businesses use it. Maybe try an auto body shop and they might be able to look it up in their supply catalog?
I did some looking around for alcohol. Here are some places to try. Bulk fuels dealer - farm, agriculture, gas station supply places. They might be able to order it. If you have an ethanol plant near you contact them. The company that I used to work for bought ethanol and isopropyl in 5 gal from lab supply companies but that was a little pricey. I would check to make sure that NAPA Car Parts doesn't have assess to it.
