I do not think this is just a passing fad. There are a lot of advantages to it, even if you don’t paint the whole car, such as airbrushed work like this. Signs, stencils, accents. It is easy and cheap. It’s easy to remove. Works good on wheels.

Automotive paint is expensive, toxic, and requires special equipment. The body must be prepared painstakingly. Sanded, smoothed, bondo applied, sanded some more, then a coat of primer.
Plasti Dip only needs a thoroughly clean surface. Can be sprayed outdoors, with some of the cheapest home sprayers. If you don’t like it, it can just be peeled off. Now, I have learned you can airbrush it with common airbrush equipment. It can be painted onto another coat of plasti dip, like in this picture. Amazing. It is also much cheaper than paint.
