I posted a while ago after trying slim to seal my tires on the suggestion of a friend that did not work. The stuff seeped out of my sidwalls. I ended up putting tubes back in forgetting it for the time being. Now I've got Stan's sealant and installed it in my tires last night with Stan's rim strips. This morning bot tires were VERY low on pressure. Just 6 hours later! Does the stuff take a while to set up and seal? Or does it just not work with my tires?
