There hasn't been enough time to tell what permanent means as far as OG goes, but I can say that I started using it as soon as it was available for me to purchase and I still regularly wash cars for people who had me apply it back then and it still looks like the day I applied it.

Don't go thinking that with OG you can just run through automatic car washes (the type with brushes) and not hurt anything, but even a touchless automatic shouldn't really affect it.
It is a resin-based coating that chemically cross-links just like clear coat as it cures, and surface abrasion is the only way to remove it.
