Blackfire products on coating

I got several Blackfire products last fall and waited all winter to use them. I applied a coating to my car (mckee`s 37) and now i am hearing that certain products can break it down or cause it to not function properly. I have blackfire quick detailer that I would like to spray on after I wash the car to help with any streaks from the hard water. I also have a carnuba paste wax from blackfire that I want to apply to give the car a fresh wax `feel` and a deeper shine. I heard from some that wax and detailer spray can be applied over this particular coating, however I have not seen it say that from mckee`s product information.

I wrote to Mckee`s and they said what I thought; to only use their detailer and their carnuba wax. I feel that there a bit of marketing in that response. What do you think?
