Thanks guys. I'm not looking for it to be perfect, after all this is a track bike and I've already slid it down the road so I'm going to limit the amount of effort I put in and use it to learn. If it goes well then I'll be wrapping my road bike too, but making a better job of that!

@WhyNot sounds like you have experience of this? I saw a video on the tube where the guy was using a small blowtorch from about 6 - 8 inches away. seemed to do the trick and get a good heat spread and plenty of stretch without burning so was thinking of getting one of those.
