could the blackfire coating go over cquartz, or would the cquartz need to be polished off?
The problem with quartz based coatings such as the BlackFire, CQuartz, and others is that they form an incredibly slick glass like surface and are non-porus. If you are going to add another coat it is suggested that is applied within an hour otherwise it may not properly bond to itself.
Imagine if you will, you take your car in for paint repair. In order for the new paint to be applied and bond correctly the surface needs to be scuffed for the paint to stick. If not, you will run into problems as the paint being laid down will not properly bond, begin to sag after a coat or two, and have runs. After a while that paint will being to flake off as it never had a proper foundation to grab onto.
Now, a coating won't behave exactly like the above paint job but it still needs a prepped surface to adhere to otherwise it will prematurely fail. What I would do is "scuff" the surface in the way of a finishing polish such as SF4000, Wolfgang FG, M205 etc with a finishing pad to make sure it is ready for application. With the surface being "scuffed" now it is ready for application of your new product. If you want to lay down a second coat make sure it is applied within 30-60 minutes. Not sooner. You want to give the product time to flash and adhere without interfering during this time.
This method will apply to all Coatings regardless of chemical makeup IMO.
