This works as well as Stan's but is more of a pain to when it comes to cleaning up. I bought this as I was trying a tire that wasn't compatible with Stan's. The cafe latex sets up and dries much quicker which is good and bad but I wouldn't say it seals any better or worse. I got a large puncture in the tire I was using and the cafe latex sprayed all over my hub, chainstays and chain guide. This dried and was a pain to get off. Furthermore it got all over the back of my calf removing a large amount of hair. All things being equal, I'd choose Stan's which scrubs or wipes off easily as opposed to spending time peeling dried rubber out of nooks and crannies.
