Optimum is not a marketing company, but I suggest the term "permanent" is just that. All coatings are permanent on garage queens or lightly driven vehicles...But you're promoting durability as the most important characteristic when appearance, ease of maintenance, resistance to marring/etching, etc are equally valuable. The obvious difference in coatings is durability, and easiest to promote, but I believe the other characteristics are just as important...and better the coating, the greater those other features.
If all you want is durability, buy Gloss-Coat and apply Hyper Seal every 6-12 months and you will have a permanent coating. Easy peasy!
I never said Opti-Coat Pro was gone, the car looks great, just that the hardness has declined so that micro-marring occurred. Normal wear & tear on a daily driver, combined with regular maintenance, AND UV have reduce the coating enough to allow minor damage.
