Whether or not the coating will last for 6 years is highly debatable. But if that coating still gets swirls in it, then what's the point, really? Unless your dad is like the vast majority of consumers and has no idea what swirls really are and/or doesn't really care if they're there or not. If you're a detailer or care care enthusiast, you don't want to see swirls in your paint at all. That means correcting as needed, and correcting swirls in a long term coating will remove the coating, so again, what's the point?
But application of an interior protectant that will make your eyes burn for the first few weeks of ownership is just inexcusable. Personally, I would have been screaming for a refund or for the dealer to take the car back. But apparently some people can more easily tolerate both burning of the eyes and a bunch of swirls than I can.
exactly, this stuff swirls even more easily than clear coat, and its more difficult to remove from my experience due to the fact its soft and deep and it feels as though youre trying to buff a phone screen protector off a car. it actually feels like a thin 3m clear film. not fun.
