FWIW, I have a little experience with Isopropol alcohol in the US. It is readily available in Pharmacys. I work with epoxy resins occaisionally. The 70% alcohol-30% water grade is very cheap, less than a dollar a bottle. I use it for clean up. The 99% is about 4 times as much and must be ordered in. That is a day or so at WalMart. I use the 99% to thin epoxy to brush it. Methyl alcohol may be better for both purposes but I don't like the feel of it on my hands.
