I dont really get this either but if you want to do it then go for it. AFter all, it will keep you off the streets which is definitely a good thing D
I would definitely suggest speaking to Japohara. He had some issues/difficulties with his (mainly the tight curvy bits from memory) which you will probably experience as well, irrespective of the colour you chose and the fact that (I presume) you are wrapping the MK1.
It's worth bearing in mind that another option for changing the colour of your motor would be to buy a sprayer. You can get hold of some epoxy paint and all you would need is masking ability and a clean garage. Depending on the spec you buy, it could be resprayed within 2 wraps and could give you a nifty side line
EDIT: meant to post this pic I have of Japo's car
