I look at that as a great way to change the look of the car, but it likely won't add much protection. It'll probably chip just like paint would, except now you might have an issue that if it chips deep enough, then it might start to peel from that chip location.
It's odd that DipYourCar is listed as a main distributor but they don't seem to use that on their youtube channel. As far as I know they still use PlastiDip as the base and then whatever gloss top coat with color or pearls. Honestly their results don't look amazing up close either. This seems to have serious orange peel effect on it, probably from the hand spray and likely the depth isn't real uniform because of the hand spray application. Probably not an issue, but if you want it to look great up close you probably need a two step paint correction after applying this. When you factor the cost for good prep (tape off all edges/remove whatever you can), spray, and paint correction, you might be at the same type of cost as paint protection film.
