hi guys, good points raised there lerch, and yup, i bought ayrton's carbon skinned bonnet....the difference between the real fibre and the wrap is night and day, the depth of shine, the weave etc are second to non, and now i wouldnt dream of adding the wrap to the roof...
that said there are other options nick, but as ever it depends on your budget.
lots of spare money will buy you a full carbon bonnet and about a million jdm points
next step down is to go for a carbon skinned bonnet, again not cheap, but an amazing result you will be very happy with,
then there is the dipping option, i cant comment on how it looks in real life, but get in touch with paul323f, he has his own dipping business and im sure he can give you all the ins and outs regarding this option.
then there is the wrap option, cheap(ish) and chearfull, this would be better if you are going for the stealth look, as from what i have seen, even the 'shiny 3D' stuff ends up with a matte finish.
ill have a look about as when i had my x3 one of the lads on the forum wrapped his roof and like lerch says, it was tricky as hell to do, and that was without a sun roof if i remember correctly.
but here is womble, shameless pic showing off, but i love it
