We were talking about this the other week in work when the matte blue 159 appeared on here, and the general opinion was that unless a serious amount of time was put into it the results would be scrappy. Yeah from a distance it would look great but up close around window seals, badges, panel edges, wheel arches etc etc unless everything was being taken off like the bumpers etc and the wrap taken in a 5mm i cant seeing it looking that good esp after a while in out wet country. Then theres the area's that arent gonna be wrapped like the B pillars and the inside faces of the doors, boot etc maybe not so bad if sticking with the same colour but again the whole point is to change the cars appearance and then you open a door to reveal a mismatch. Ive worked with decals and vinyls before and i know theve came on loads in recent years but i cant see it being 100%. Im not saying its not possible to do it but the amount of effort to do it right and time involved and the cost id be thinking of a full respray. Thats just my opion and I hope they do a good job for you, hopefully im wrong.
