I have used this sealant on many customer bikes and have loved it, never had a problem until I bought it for my MTB wheels. These are WTB "tubeless ready" (haha) wheels on my Fuji Reveal 1.0 and they were leaking from every spoke hole and weld. After a long time, the wheels were finally tight, and here came the problem: I didn't clean the wheels right away because I didn't want them to leak again. The next morning I went to remove the gasket from the wheels and a) it had set like dried glue and b) there was corrosion and peeling paint on many of the spoke nipples. Next time I do a tubeless service it will be Stan or someone else.
