I've been making talc barriers and have almost completley run out of isopropyl alcohol. I've been using the 91% isopropyl alcohol, but does the amount of alcohol in the bottle effect the result of the barrier? I found a quarter full bottle of 99% isopropyl alcohol, but I didn't know whether to use it or not. Thanks in advanced.
