WTB Vulpine tubeless setup - sidewall strenght?

Funny. I just mounted a set of vulpines on some stans arch rims. I am using the effetto cafelatex sealant. So far this is the worst tire I have ever tried to seal. The sidewalls were nearly white so much sealant was seeping through. In the morning, one tire had lost all of its air. Re-inflated and went for a ride today. Held pretty well but as I hit a gravel area near the house I heard a massive hissing and sealant started to spew out several spots in the sidewall. Eventually sealed but a lot of pressure escaped. Re-inflated the tires and they have held pressure since. So far the jury is out on the ability to run vulpines tubeless IMO.

I have decided to bail on getting these things to work. One tire is holding air fine on a stans arch rim. the other, while trying again to get an effective seal, blew the bead out of the rim. sounded like a huge gunshot. blew the wheel out of my hand and across the garage. it now has a tube and i won't be trying to seal that tire again.......

Thanks for the follow up

Found this post 'cause the jury's out for me also regarding a set of Vulpines running tubeless on Stan's Arch rims. One tire is great—zero leaks. The other? Seeping through the sidewalls...can't get it to seal. Added more sealant...still leaking.
