Hi Neil,
All valid points and if you want a replacement piece for the bonet we can come to an arrangement. I'd rather you were happy with it and your car was covered
As for the bonet lip, yes it is by far the toughest of the pieces but a hair dryer to heat it up, or even on a hot day will make the material extremely flexible to allow it to bend over the curves with out too much trouble. It is the only piece out of all of them which will need a some patience, the VX is particularly square on all the other panels. As for bubbles and alcohol solution, using alcohol will just allow the solution to dry quicker, great if you are experience, not so much if you are not. using soap and water will allow you to keep moving it around until you are happy with it's placement and then proceed to squeeze the solution out. If you had used alcohol you may find that it had dried and started to cure the adhesive before you had finished with the positioning.
As for bubbles and clouding etc, this will dry out over a few hours. If anyone else who has fit these ( good or bad experience ) wants to chime in to offer others advice, please do.
