Smart Detail in Toronto did a great job. This was their first dry application of Hyper Seal, as they'd only previously used it as a drying agent. And, he had one bottle for sale, so I got it. I have now put on my second coat and the car looks fabulous - with a deep gloss unlike anything I've used before. I used ONR to wash, and the paint definitely had a different texture, almost like an oily (but not actually oily) hydrophobic surface. The ONR actually sheeted off.
I've made a couple of assumptions about application since there is nothing published yet about Hyper Seal:
I assume that I should use it the same way as Opti-Seal and apply three coats. The second layer is on. Waiting 24 hours and adding another. Thereafter, topping up periodically until the next detail.
The dealer suggested half a spray per panel. I worked this in extremely well with a MF towel and went over with dry side to remove any final residue.
So far, I'm very impressed.
