Threebond products seems to be very challenging to get hold at least to people living outside US or central Europe.
I managed to buy Hondabond 4 (Threebond 1184) from dealer who will actually ship it, but still searching for 1215. Loctite products are available everywhere here so buying e.g. 574 is very easy, and I will most likely use that on case sealing flanges. (also Wurth products are available)
Is there tried and tested Loctite product that is alternative to Threebond 1215? And to Curil T?
I'm not trying to save any penny, I'm just sure there are good alternative (OEM) products here for engines made in Germany.
Edit. I faund 1215 now also, but I still think question is valid
