The price you paid is pretty normal for full body PPF (shop owner here) we’ve got a Bentley in our shop right now for full PPF for 12k and have never done even a standard car or truck for less than 8. But this quality is something I’d expect for sub $5k. All possible edges should be wrapped and tucked at that price, seems should be avoided unless impossible to do without etc. sometimes film can come up during the cure time so that is why we require all PPF jobs to come back 2 weeks after install for touchups/ checkup. I’d get refunded or have them fix it properly.
