Im planning on wrapping the octy after christmas and for £129 for 10m roll seems rude not to rather than going for a respray, was wondering if anyone has had any experience with diy car wrapping, any advice or techniques will be greatly appreciated :-)

It's best to wrap when the weather is warmer, takes the curves better.  You can use a heat gun or hair drier but the whole job will take longer.   if you are wrapping in the garage all the better, heat the garage up first.  Any dents, dings do show up more with a wrap on top.   the car has to be completely clean & dry.
