That’s not true. If you don’t know how to do it properly it’ll come out looking like shit and you’ve just wasted all your time and money. Not to mention the vinyl will and can get scratched off, where as paint can be buffed out. You can get bubbles, creases, folds, tears, big scratches…all factors while putting the vinyl on, imagine what could happen when it’s finished. Try cutting out a section that may have gotten ripped and replacing it with another piece…it won’t look anywhere close to proper. I’d strongly suggest painting your car unless your only do a few body parts.
EDIT: Have you ever put on a small sticker and there’s a couple bubbles underneath it but don’t know how to get it out? Or if somehow some small debris got underneath it and your stuck on what to do? Imagine what can happen with an entire wrap.
