On our 2019 Charger Scat Pack, we had our go-to window tint folks do the clear wrap on the front bumper cover. We ran it through a very nice car wash with brushes all the time. It did just fine.
Like the stuff on our car, if you had tint especially designed for those uses installed professionally, it would likely stay in place. Or at least the folks installing it would tell you its limits. I suspect there is a big difference in high quality film designed for external use, and the rest of the stuff we can buy and install ourselves.
