Ok, so I am an old f**t, but I don't get it.
The manufacturers of cars spend millions on the research & development of paint & generally do a great job & then someone buys a car & covers it in glorified cling film! Surely if you really dislike the colour then a) buy one in the colour you like, or b) have a professional respray, done correctly that's a permanent solution.
I don't know what the wrapping stuff is, but having run business's where the vans are sign written, rest assured, if it's similar stuff even the most professional job has a limited shelf life.
The owner then puts on an illegal set of number plates & possibly windows that are too dark & therefore illegal & will complain if (or rather, when) the police "harass" him with stops.
But as I say, I am just a boring old f**t & like my vehicles basically factory standard, so what do I know!
