First of all the bicycle tube repair glue is speed glue basically as already mentioned. The fumes use to expand the sponge, which gives you more speed and spin. I would not use this in 2015. The effects only last few hours and it's a pain in the ass to remove, especially if you like me boost and reglue often.
I will suggest instead you get some lamp oil which will give you similar effects, soften, expand the sponge, give wetness which is often described as rubber being alive (this feeling is exaggerated with brand new sealed rubber for about 2 weeks) which will in itself increase the speed and spin and change the attributes of the rubber slightly. For example 47 hardness becoming 45 shore. And here is the reasons why this method is better today. The effect will last 2+ up to 4 weeks. Keep your blade vacuum sealed after matches to preserve the boost for longest. Combine that with easy to apply and remove water based glue, this is the best process in my opinion. Even if it doesn't give the same amount of speed as tyre glue.
