Stans supply schwalbe and IRC and may be so.e other with there sealant. I just remember it failing to seal often but topping up often cured that. It main issue is dropping latex so the fluid is latex poor and that why it had issues. At the time I was using a rim that required compressed air to get the tyre to inflate. That was the issue. Co2 was deadly. I sometimes helped seal the tyre but also meant I had to top up again at home
That what led me to think stop relying on sealant.
Yeah I wouldn't roll a turd in glitter. In that case what's the test approved sealant? I've never had issues with Stans so far mind, except for maybe it not lasting all that long.
