You can probably get it from Home Depot or something, I have a giant square can of it that looks to be a few years old so I don't remember where I got it. Just don't drink it and wash your hands afterwards, I think it evaporates pretty quickly too. BTW I'm pretty sure the Arctic Silver directions recommend mineral spirits or isopropyl alcohol, either should be fine.
