I know the detailer and he does it all the time on exotic cars...I poured water on it and it was like there was no protection and he paid over $600 on a brand new Subaru BRZ for this protection.
Some one did something wrong... OC Pro is amazing. My self and all the other pro installers wouldn't be charging the prices we do if it wasn't. I've use OC 2.0(consumer version) as well it's a great product to. 2.0 is more forgiving during the application learning curve. I don't know said detailer but he screwed up point blank. You could give him my contact info, Chris Thomas, or Dr G's for advice because if what you say is true he failed at install.
