PhilGrmPa - If you are in the US, either Nova or April's products are likely not as prohibitive to try as they are for me. Once I figure in shipping to Canada and then the exchange on top plus undoubtedly duty - and that's even if I COULD get them across the border ... well let's just say I'm not going to be testing them. I'd be interested if someone could let us know what their melting points are. I have a suspicion but this is a public forum and rules and all.
I keep meaning to take a motor in and hit an electric motor shop but quite frankly Dec and Jan have really been the sh*ts for us and it's just slipped my mind repeatedly. Perhaps I'll put a motor in my bag and hope it prompts me the next time I'm out. That should garner a few questions from DH when he sees it sitting there.
ETA: Yeah, anything with zinc oxide in it would be off my list too. Isn't that what you put on your nose on the ski hill to stop it (your nose, not the hill) from burning?
