How long does BULLFROG SNOT remain functional in operations is a good question. I don't really know, as I've been running the pre-production batch of brew on my layout since last October. And it still pulls like an Ox. I have replaced a few tires, but mostly just for drill not because it was necessary. I don't know when it wears out, as I haven't found that point yet.
Any comments out there? A lot of BULLFROG SNOT is now doing it's job on many model empires, but we have received zero reports about when it quits. There were a lot of doubters when it was first released, but to date no complaints from actual users.
I did hear of a few that have managed to seal their jar of BULLFROG SNOT shut. Hey, be careful with this stuff and keep it off the threads, it really grips.
