From the Stan's website they recommend unscrewing the top brass thumb screw with pliers. After assembling the core, they recommend you take a pair of pliers and on the last few threads gently squeeze the threads to damage them so the brass thumb screw will not fall off. Will try these steps tomorrow. Thanks! Was just researching tube sealants and can across these great instructions.

Joe blow piece usage ended up resulting in sliming the kitchen (where I was performing bike maintenance), but it did work. I need to purchase the adapter, or it would be nice if Slime provided one for presta (adapter or tube size...what ever). The sliming was mostly due to the high squeeze/pressure I had to apply to the bottle to get some flow going. Actually loosing the presta insert in the tube aided in getting flow going. So on second tube I just lost it and then found it and stuck it back in place. Not a big deal. Good luck!

I injected slime into my schrader tubes by folding the tube so that there was a "corner" and cutting off the very tip so that there was a tiny hole in the tube. I then pushed the slime bottle tip into this (the hole had to stretch) to fill them up and finished the job with a patch! My tubes have been fine and they must have been in for 2 years or more. I ride most weeks off road so they get some abuse too - can't complain! Slime has pros and cons, and I prefer tuffy tape for my commuter bike or puncture resistant tyres. But for training cross country and riding a lot of bridleways where thorns are common I think slime is the way to go. Slime has saved me loads of time fixing punctures (at night) on the trail. I then tend to inspect my tyres at home where I can fix any holes out of the rain and in the comfort of my garage with the radio on. Hope this helps! The primitive approach!!!

After throwing the mess I made aside and going back to it the next day, I finally got the shaft into the valve stem. I noticed that the thread moved ever so slightly when I pinched the tube on one side of the stem and not on the other side. This was very subtle but it was noticeable. It's kind of like watching your leader when flyfishing nymph patterns for all you flyfishers. I cleared the stem with an allen wrench handle and I tilted the valve stem end away from the side that the shaft was in. I gently tugged the thread a few times and, presto, the shaft fell into place. I was then able to pull it down enough to thread the knurled nut onto the shaft and was able to inflate it no problem. Problem solved. I take it this is the worst case scenario of getting slime into a presta tube so maybe others in the same situation can benefit. Update.

I say TRIED because it was not physically possible. There is no 'tapered funnel opening' in the top of the bottle. It is untapered and so you cannot screw the valve threads into it. I had to wrap the threads with teflon tape to get somewhat of a seal. Next I had to poke the shaft into the tube with a toothpick and keep stopping and doing that so I could get a small amount of slime in there before it blocked up the valve with a wad of fibers. Finally, even though I tied a thread to the end of the shaft as suggested here, I could not get the shaft out again. This was a heavy duty thorn proof tube so I can't feel the shaft in there at all to manipulate it into the valve stem. I will not waste any more time with Slime. I will get a $50 kevlar tire and another heavy duty tube. That should work better anyway. I just TRIED to follow the instructions on Slime’s website for presta valves.

I forgot to re-install the nut before inflating the tube and it came out of the valve and I had to use my fingers to manuever it back into the valve, then I put the nut back on and inflated the tube. I put about 2 t o 3 ounces of slime in each 700cx23 tube. The Slime website says to put 4 ounces in bicycle tires, they dont say how much for different size tubes though.
