Nice to have another Canadian join the ranks! Greetings from BC!
Have you tried Udisco in Montreal? I thought they carried Micro Sol & Set? Micro Set is definitely a vinegar base!
There are other kinds: Mr. Softer from Gunze, Solvaset, Decal Softer, Testors makes a line too. Many of them are acetic acid based (vineger) and some get "hotter" and use an alcohol base.
If you have a real hard time, email or PM me and I'll pop some in the snail mail for you. My LHS usually has numerous bottles on hand.
